# officecli

AI-friendly CLI for .docx, .xlsx, .pptx. Single binary, no dependencies, no Office installation needed.

## Install

If `officecli` is not installed:

```bash
# macOS / Linux
curl -fsSL https://d.officecli.ai/install.sh | bash

# Windows (PowerShell)
irm https://d.officecli.ai/install.ps1 | iex
```

Verify with `officecli --version`. If still not found after install, open a new terminal.

---

## Strategy

**L1 (read) → L2 (DOM edit) → L3 (raw XML)**. Always prefer higher layers. Add `--json` for structured output.

**Before doc work, check Specialized Skills** (bottom of this file). Fundraising decks, academic papers, financial models, dashboards, and Morph animations need their own skill loaded first — `load_skill` once, then proceed.

---

## Help System (IMPORTANT)

**When unsure about property names, value formats, or command syntax, ALWAYS run help instead of guessing.** One help query beats guess-fail-retry loops.

`officecli help` ≡ `officecli --help`, and `officecli <cmd> --help` ≡ `officecli help <cmd>` — same content.

```bash
officecli help                                  # All commands + global options + schema entry points
officecli help docx                             # List all docx elements
officecli help docx paragraph                   # Full schema: properties, aliases, examples, readbacks
officecli help docx set paragraph               # Verb-filtered: only props usable with `set`
officecli help docx paragraph --json            # Structured schema (machine-readable)
```

Format aliases: `word`→`docx`, `excel`→`xlsx`, `ppt`/`powerpoint`→`pptx`. Verbs: `add`, `set`, `get`, `query`, `remove`. MCP exposes the same schema via the single `command` string param: `{"command":"help docx paragraph"}` (not a structured `{"format":...,"type":...}` object — the MCP tool has exactly one param, `command`, and passes it through to the CLI verbatim).

---

## Performance: Resident Mode

**Every command auto-starts a resident on first access** (60s idle timeout) — file-lock conflicts are automatically avoided. Explicit `open`/`close` is still recommended for longer sessions (12min idle):
```bash
officecli open report.docx       # explicitly keep in memory
officecli set report.docx ...    # no file I/O overhead
officecli close report.docx      # save and release
```

Opt out of auto-start: `OFFICECLI_NO_AUTO_RESIDENT=1`.

**Flush only at the non-officecli boundary.** officecli's own reads (`get`/`query`/`view`/`dump`) always see your latest edits, so you never need to save mid-workflow. Run `save` (keeps the resident) or `close` (flush + release) only **before a non-officecli program reads the file** — python-docx/openpyxl, Word, a renderer, delivery/upload. (Idle sessions auto-flush within seconds; `OFFICECLI_RESIDENT_FLUSH=each` makes every mutation flush before returning.)

---

## Quick Start

**PPT:**
```bash
officecli create slides.pptx
officecli add slides.pptx / --type slide --prop title="Q4 Report" --prop background=1A1A2E
officecli add slides.pptx '/slide[1]' --type shape --prop text="Revenue grew 25%" --prop x=2cm --prop y=5cm --prop font=Arial --prop size=24 --prop color=FFFFFF
```

**Word:**
```bash
officecli create report.docx
officecli add report.docx /body --type paragraph --prop text="Executive Summary" --prop style=Heading1
officecli add report.docx /body --type paragraph --prop text="Revenue increased by 25% year-over-year."
```

**Excel:**
```bash
officecli create data.xlsx
officecli set data.xlsx /Sheet1/A1 --prop value="Name" --prop bold=true
officecli set data.xlsx /Sheet1/A2 --prop value="Alice"
```

---

## L1: Create, Read & Inspect

```bash
officecli create <file>               # Create blank .docx/.xlsx/.pptx (type from extension)
officecli view <file> <mode>          # outline | stats | issues | text | annotated | html
officecli get <file> <path> --depth N # Get a node and its children [--json]
officecli query <file> <selector>     # CSS-like query
officecli validate <file>             # Validate against OpenXML schema
```

### view modes

| Mode | Description | Useful flags |
|------|-------------|-------------|
| `outline` | Document structure | |
| `stats` | Statistics (pages, words, shapes) | |
| `issues` | Formatting/content/structure problems | `--type format\|content\|structure`, `--limit N` |
| `text` | Plain text extraction | `--start N --end N`, `--max-lines N` |
| `annotated` | Text with formatting annotations | |
| `html` | Static HTML snapshot — same renderer as `watch`, no server needed | `--browser`, `--page N` (docx), `--start N --end N` (pptx) |
| `screenshot` / `svg` / `pdf` / `forms` | PNG via headless browser / SVG (pptx slide) / PDF via exporter plugin / form-fields JSON via format-handler plugin | `-o`, `--screenshot-width/-height`, pptx `--grid N` |

Use `view html` for one-shot snapshots (CI artifacts, archival, diffing); use `watch` when you need live refresh or browser-side click-to-select.

### get

Any XML path via element localName. Use `--depth N` to expand children. Add `--json` for structured output. Default text output is grep-friendly: `path (type) "text" key=val key=val ...`

```bash
officecli get report.docx '/body/p[3]' --depth 2 --json
officecli get slides.pptx '/slide[1]' --depth 1          # list all shapes on slide 1
officecli get data.xlsx '/Sheet1/B2' --json
```

### Stable ID Addressing

Elements with stable IDs return `@attr=value` paths instead of positional indices. Prefer these in multi-step workflows — positional indices shift on insert/delete, stable IDs do not.

```
/slide[1]/shape[@id=550950021]                    # PPT shape
/slide[1]/table[@id=1388430425]/tr[1]/tc[2]       # PPT table
/body/p[@paraId=1A2B3C4D]                         # Word paragraph
/comments/comment[@commentId=1]                    # Word comment
```

PPT also accepts `@name=` (e.g. `shape[@name=Title 1]`), with morph `!!` prefix awareness. Elements without stable IDs (slide, run, tr/tc, row) fall back to positional indices.

### query

CSS-like selectors: `[attr=value]`, `[attr!=value]`, `[attr~=text]`, `[attr>=value]`, `[attr<=value]`, `:contains("text")`, `:empty`, `:has(formula)`, `:no-alt`. Boolean `and`/`or` supported across `query`/`set`/`remove`: `cell[value>5000 or value<100]`, `cell[(type=Number or type=Date) and value>0]`. Excel row-by-column-name: `Sheet1!row[Salary>5000]`. `set` accepts selectors and Excel-native paths (parity with `get`/`query`). Bare unscoped selectors rejected on `set`/`remove`.

```bash
officecli query report.docx 'paragraph[style=Normal] > run[font!=Arial]'
officecli query slides.pptx 'shape[fill=FF0000]'
```

---

## Watch & Interactive Selection

Live HTML preview that auto-refreshes on every file change. Browsers can click / shift-click / box-drag to select shapes; the CLI can read the current browser selection and act on it.

```bash
officecli watch <file> [--port N]      # Start preview server (default port 26315)
officecli unwatch <file>               # Stop
officecli goto <file> <path>           # Scroll watching browser(s) to element (docx: p / table / tr / tc)
```

Open the printed `http://localhost:N` URL. Click to select; shift/cmd/ctrl+click to multi-select; drag from empty space to box-select. PPT/Word use blue outline; Excel uses native-style green selection (double-click cell to edit inline; drag a chart to reposition).

### `get <file> selected` — read what the user clicked

```bash
officecli get <file> selected [--json]
```

Returns DocumentNodes for whatever is currently selected. Empty result if nothing selected. Exit code != 0 if no watch is running.

```bash
# User clicks shapes in the browser, then asks "make these red"
PATHS=$(officecli get deck.pptx selected --json | jq -r '.data.Results[].path')
for p in $PATHS; do officecli set deck.pptx "$p" --prop fill=FF0000; done
```

### Key properties

- **Selection survives file edits.** Paths use stable `@id=` form.
- **All connected browsers share one selection.** Last-write-wins.
- **Same-file single-watch.** A given file can have only one watch process at a time.
- **Group shapes select as a whole.** Drilling into individual children of a group is not supported in v1.
- **Coverage:** `.pptx` shapes/pictures/tables/charts/connectors/groups; `.docx` top-level paragraphs and tables. Inherited layout/master decorations and Word nested elements (table cells, run-level) are not addressable. **`.xlsx` does not emit `data-path`** — `mark`/`selection` on xlsx always resolve `stale=true` (v2 candidate).

### Marks — edit proposals waiting for review

Use `mark` when changes need human review BEFORE they hit the file. Marks live in the watch process only; a separate `set` pipeline applies accepted ones. For one-shot changes use `set` directly; for permanent file annotations use `add --type comment` (Word native).

```bash
officecli mark <file> <path> [--prop find=... color=... note=... tofix=... regex=true] [--json]
officecli unmark <file> [--path <p> | --all] [--json]
officecli get-marks <file> [--json]
```

Props: `find` (literal or regex when `regex=true`; raw form `find='r"[abc]"'`), `color` (hex / `rgb(...)` / 22 named whitelist), `note`, `tofix` (drives apply pipeline). **Path** must be `data-path` format from watch HTML — see subskills for full pipeline.

---

## L2: DOM Operations

### set — modify properties

```bash
officecli set <file> <path> --prop key=value [--prop ...]
```

**Any XML attribute is settable** via element path (found via `get --depth N`) — even attributes not currently present. Without `find=`, `set` applies format to the entire element.

**Value formats:**

| Type | Format | Examples |
|------|--------|---------|
| Colors | Hex (with/without `#`), named, RGB, theme | `FF0000`, `#FF0000`, `red`, `rgb(255,0,0)`, `accent1`..`accent6` |
| Spacing | Unit-qualified | `12pt`, `0.5cm`, `1.5x`, `150%` |
| Dimensions | EMU or suffixed | `914400`, `2.54cm`, `1in`, `72pt`, `96px` |

**Dotted-attr aliases** — `font.<attr>` forms accepted on shape/run/paragraph/table/row/cell/section/styles, e.g. `--prop font.color=red --prop font.bold=true --prop font.size=14pt`. Run `officecli help <fmt> <element>` for the full list.

### find — format or replace matched text

Use top-level `--find` / `--replace` on `set` (and `--find` on `query`). Legacy `--prop find=X` still works but emits a hint.

```bash
# Format matched text (auto-splits runs)
officecli set doc.docx '/body/p[1]' --find weather --prop bold=true --prop color=red

# Regex matching (regex= still a prop flag)
officecli set doc.docx '/body/p[1]' --find '\d+%' --prop regex=true --prop color=red

# Replace text (use `/` for whole-document scope)
officecli set doc.docx / --find draft --replace final

# docx: tracked Find&Replace
officecli set doc.docx / --find draft --replace final --prop revision.author=Alice

# PPT — same syntax, different paths
officecli set slides.pptx / --find draft --replace final
```

**Path controls search scope:** `/` = whole document, `/body/p[1]` or `/slide[N]/shape[M]` = specific element, `/header[1]` / `/footer[1]` = headers/footers.

**Notes:**
- Case-sensitive by default. Case-insensitive: `--prop 'find=(?i)error' --prop regex=true`
- Matches work across run boundaries
- No match = silent success. `--json` includes `"matched": N`
- **Excel:** only `find` + `replace` supported (no find + format props)

### add — add elements or clone

```bash
officecli add <file> <parent> --type <type> [--prop ...]
officecli add <file> <parent> --type <type> --after <path> [--prop ...]   # insert after anchor
officecli add <file> <parent> --type <type> --before <path> [--prop ...]  # insert before anchor
officecli add <file> <parent> --type <type> --index N [--prop ...]        # 0-based position (legacy)
officecli add <file> <parent> --from <path>                               # clone existing element
```

`--after`, `--before`, `--index` are mutually exclusive. No position flag = append to end.

**Element types (with aliases):**

| Format | Types |
|--------|-------|
| **pptx** | slide (incl. hidden), shape (font.latin/ea/cs, direction=rtl, underline.color, highlight=COLOR (Add/Set/Get/HTML preview), effective.X+effective.X.src; arrow alias for rightArrow; slideMaster/slideLayout typed add/set/remove), picture (SVG, brightness/contrast/glow/shadow, rotation, link, tooltip), chart (direction=rtl, pieOfPie, barOfPie, axisLine/gridline per-attr setters, animation+chartBuild=byCategory|bySeries, line dropLines/hiLowLines/upDownBars, anchor=x,y,w,h shorthand), table (cell direction=rtl, fill/background, built-in PowerPoint style catalogue, /col[C] get + swap/copyFrom, row/col Move/CopyFrom), row (tr), connector (from/to accept full-path `@name=`/`@id=` forms — bare `@name=Foo` is rejected, must be `/slide[N]/shape[@name=Foo]` — startshape/endshape SetByPath; edge-to-edge anchoring by default, fromSide/toSide to force an edge, fromIdx/toIdx for raw cxn index), group (link, tooltip, deep walk by get/query/add/remove, ungroup=true dissolves back to slide-absolute), align/distribute (targets= accepts shape[@id=N] paths, not just positional), video/audio (loop, autoStart alias), equation, notes (direction=rtl, lang), comment (legacy + modern p188 threaded round-trip), animation (15 emphasis + 16 exit presets, multi-effect chains, motion-path presets, repeat/restart/autoReverse, chart animations), transition (12 p15 presets + morph/p14), paragraph (para), run, zoom, ole (preview=, full dump round-trip via add-part+raw-set), placeholder (phType=...), model3d (rotation=ax,ay,az; full dump round-trip), smartart (dump round-trip via add-part), diagram (add-only mermaid → native shapes or rendered image, `--type diagram`/`flowchart`). |
| **docx** | paragraph (direction/font.latin/ea/cs, bold.cs/italic.cs/size.cs, lang.latin/ea/cs, wordWrap, framePr.\*, tabs shorthand), run (lang slots, direction, underline.color, position half-pts, **revision.type=ins\|del\|format\|moveFrom\|moveTo + revision.action=accept\|reject** with .author/.date — bare `@author=`/`@type=` selector on `set /revision[...]` for filtered accept/reject, but `query 'revision[...]'` needs the dotted `revision.author=`/`revision.type=` form; move+revision is run-level paths only, not paragraph-level; **range=START:END** on a paragraph/shape path formats a char span by explicit 0-based half-open offset instead of addressing a run — the offset sibling of find=), table (direction=rtl, hMerge, cantSplit on row/nowrap on cell (both add+set), **virtual column ops**: add/remove/move/copyfrom on /body/tbl[N]/col), row (tr), cell (td), image, header/footer (direction), section (pageNumFmt full enum, direction=rtl, rtlGutter, pgBorders=box), bookmark, comment, footnote, endnote, formfield, sdt, chart, equation, field (28 types), hyperlink, style (direction, indents, pbdr, lineSpacing on Add/Set), toc, watermark, break, ole, **num/abstractNum/lvl**, **tab**, **textbox/shape** (add-mostly — Get returns raw XML preview only, no structured readback; Set is limited to width/height/geometry/fill/line.\*; position is `anchor.x`/`anchor.y` not bare x/y; **textbox-only** `textDirection`/rotation/gradient/shadow — docx shape itself has neither rotation nor gradient), embedded **OLE round-trip on dump→batch**, **diagram** (add-only mermaid → native shapes or rendered image, `--type diagram`/`flowchart`, no x/y at add-time — reposition via `set /body/group[N]`). docDefaults.rtl, autoHyphenation, `get /` exposes locale + /comments /footnotes /endnotes. `create --minimal` for raw OOXML scaffolding. |
| **xlsx** | sheet (visible/hidden/veryHidden, print margins, printTitleRows/Cols, rightToLeft sheetView, cascade-aware rename), row (c{N}= cell-content shorthand; add accepts --from /Sheet/col[L]; formula-ref rewrite on insert), col (formula-ref rewrite, named-range follow on move), cell (type=richtext+runs, merge=range/sweep, direction=rtl, phonetic; **--shift left\|up on remove, shift=right\|down on add** — Excel UI dialog parity; formula auto-detect; OFFSET/INDIRECT in calc), chart (per-axis RTL/title, anchor=x,y,w,h, pareto), image (SVG), comment (direction=rtl), table (listobject), namedrange (definedname, volatile, `[@name=X]`; formula-body inlined at parse), pivottable (cache CoW + cross-pivot sharing, labelFilter=field:type:value add-time-only, topN=integer add-time-only, fillDownLabels is an alias of repeatLabels not a separate feature, calculatedField), sparkline, validation, autofilter, shape, textbox, CF (databar/colorscale/iconset/formulacf/cellIs/topN/aboveAverage), ole, csv. Query supports `merge`/`mergedrange`. Workbook: password. Shape selector enumerates leaves inside grpSp. |

### Pivot tables (xlsx)

```bash
officecli add data.xlsx /Sheet1 --type pivottable \
  --prop source="Sheet1!A1:E100" --prop rows=Region,Category \
  --prop cols=Year --prop values="Sales:sum,Qty:count" \
  --prop grandTotals=rows --prop subtotals=off --prop sort=asc
```

Key props: `rows`, `cols`, `values` (Field:func[:showDataAs]), `filters`, `source`, `position`, `layout` (compact/outline/tabular), `repeatLabels`, `blankRows`, `aggregate`, `showDataAs` (percent_of_total/row/col, running_total), `grandTotals`, `subtotals`, `sort`. Aggregators: sum, count, average, max, min, product, stdDev, stdDevp, var, varp, countNums. Date columns auto-group. Run `officecli help xlsx pivottable` for full schema.

### Document-level properties (all formats)

```bash
officecli set doc.docx / --prop docDefaults.font=Arial --prop docDefaults.fontSize=11pt
officecli set doc.docx / --prop protection=forms --prop evenAndOddHeaders=true
officecli set data.xlsx / --prop calc.mode=manual --prop calc.refMode=r1c1
officecli set slides.pptx / --prop defaultFont=Arial --prop show.loop=true --prop print.what=handouts
```

Run `officecli help <format> /` for all document-level properties (docDefaults, docGrid, CJK spacing, calc, print, show, theme, extended).

### Sort (xlsx)

```bash
officecli set data.xlsx /Sheet1 --prop sort="C desc" --prop sortHeader=true
officecli set data.xlsx '/Sheet1/A1:D100' --prop sort="A asc" --prop sortHeader=true
```

Format: `COL DIR[, COL DIR ...]`. Rejects ranges with merged cells or formulas. Sidecar metadata (hyperlinks, comments, conditional formatting, drawings) follows rows automatically.

### Text-anchored insert (`--after find:X` / `--before find:X`)

Locate an insertion point by text match within a paragraph. Inline types (run, picture, hyperlink) insert within the paragraph; block types (table, paragraph) auto-split it. PPT only supports inline.

```bash
# Word: inline run after matched text
officecli add doc.docx '/body/p[1]' --type run --after find:weather --prop text=" (sunny)"

# Word: block table after matched text (auto-splits paragraph)
officecli add doc.docx '/body/p[1]' --type table --after "find:First sentence." --prop rows=2 --prop cols=2
```

### Clone

`officecli add <file> / --from '/slide[1]'` — copies with all cross-part relationships.

### move, swap, remove

```bash
officecli move <file> <path> [--to <parent>] [--index N] [--after <path>] [--before <path>]
officecli swap <file> <path1> <path2>
officecli remove <file> '/body/p[4]'
```

When using `--after` or `--before`, `--to` can be omitted — the target container is inferred from the anchor.

### batch — multiple operations in one save cycle

Continues on error by default (returns exit 1 if any item fails). Use `--stop-on-error` to abort on the first failure. `--force` is the docx-protection bypass.

`officecli dump <file> [<path>]` emits a replayable batch JSON for round-trip — `.docx` (full coverage), `.pptx` (text/tables/pictures/charts/notes/theme + OLE/3D/video/audio/SmartArt/morph/p15 transitions via raw-set passthrough), and `.xlsx` (cells/formulas/styles + tables, conditional formatting, validations, comments, charts, sparklines, pictures, shapes, pivot tables; slicers/chartEx/OLE via verbatim carrier). Path defaults to `/` (whole document); pass a subtree path (docx: `/body`, `/body/p[N]`, `/body/tbl[N]`, `/theme`, `/settings`, `/numbering`, `/styles`; xlsx: `/SheetName`, `/sheet[N]`) to scope the dump. `officecli refresh <file.docx>` recalculates TOC page numbers / PAGE / cross-references after replay (Word backend on Windows; headless-HTML fallback elsewhere). `officecli plugins list` extends support to `.doc`, `.hwpx`, `.pdf` export.

```bash
echo '[
  {"command":"set","path":"/Sheet1/A1","props":{"value":"Name","bold":"true"}},
  {"command":"set","path":"/Sheet1/B1","props":{"value":"Score","bold":"true"}}
]' | officecli batch data.xlsx --json

officecli batch data.xlsx --commands '[{"op":"set","path":"/Sheet1/A1","props":{"value":"Done"}}]' --json
officecli batch data.xlsx --input updates.json --force --json
```

Supports: `add`, `set`, `get`, `query`, `remove`, `move`, `swap`, `view`, `raw`, `raw-set`, `validate`. Fields: `command` (or `op`), `path`, `parent`, `type`, `from`, `to`, `index`, `after`, `before`, `props`, `selector`, `mode`, `depth`, `part`, `xpath`, `action`, `xml`.

---

## L3: Raw XML

Use when L2 cannot express what you need. No xmlns declarations needed — prefixes auto-registered.

```bash
officecli raw <file> <part>                          # view raw XML
officecli raw-set <file> <part> --xpath "..." --action replace --xml '<w:p>...</w:p>'
officecli add-part <file> <parent>                   # create new document part (returns rId)
```

`raw-set` actions: `append`, `prepend`, `insertbefore`, `insertafter`, `replace`, `remove`, `setattr`. Run `officecli help <format> raw` for available parts.

---

## Common Pitfalls

| Pitfall | Correct Approach |
|---------|-----------------|
| `--name "foo"` | Use `--prop name="foo"` — all attributes go through `--prop` |
| Unquoted `[N]` paths in zsh/bash | Always quote: `'/slide[1]'` or `"/slide[1]"` (shell glob-expands brackets) |
| PPT `shape[1]` for content | `shape[1]` is typically the title placeholder. Use `shape[2]+` for content shapes |
| `/shape[myname]` | Name indexing not supported. Use numeric index or `@name=` (PPT only) |
| Guessing property names | Run `officecli help <format> <element>` to see exact names |
| Modifying an open file | Close the file in PowerPoint/WPS first |
| `\n` in shell strings | Use `\\n` for newlines in `--prop text="..."` |
| `$` in shell text | `--prop text="$15M"` strips `$15`. Use single quotes: `--prop text='$15M'`, or heredoc batch |

---

## Specialized Skills

`officecli load_skill <name>` — output is a SKILL.md, follow its rules.

**Loading rule**:
- Pick the most specific match in "When to use"; if none fits, load the format default (`word` / `pptx` / `excel`).
- Scenes already contain the format default's rules — load **one** skill per artifact, never stack.
- Loaded rules persist across turns; don't re-load each reply.
- Two distinct artifacts → two separate loads.

### Word (.docx)

| Name | When to use |
|------|-------------|
| `word` | Reports, letters, memos, proposals, generic documents |
| `academic-paper` | Journal / conference / thesis: APA / Chicago / IEEE / MLA citations, equations, SEQ + PAGEREF cross-refs, multi-column journal layout, bibliography. NOT for business reports or letters (route those to `word`) |

### PowerPoint (.pptx)

| Name | When to use |
|------|-------------|
| `pptx` | Generic decks: board reviews, sales decks, all-hands, product launches |
| `pitch-deck` | **Fundraising only** — seed / Series A-C / SAFE / convertible / strategic raise. NOT for sales / product / board decks (route those to `pptx`) |
| `morph-ppt` | Cinematic Morph-animated presentations. NOT for static decks (route those to `pptx`) |
| `morph-ppt-3d` | 3D Morph: GLB models, camera moves, depth. NOT for 2D-only Morph (route those to `morph-ppt`) |

### Excel (.xlsx)

| Name | When to use |
|------|-------------|
| `excel` | Generic workbooks, formulas, pivots, trackers |
| `financial-model` | Financial models, scenarios, projections. NOT for general data analysis (route those to `excel`) |
| `data-dashboard` | CSV/tabular data → KPI / analytics / executive dashboards with charts and sparklines. NOT for raw data tracking (route those to `excel`) |

Example: a fundraising deck task → `officecli load_skill pitch-deck` → use the printed rules.

---

## Notes

- Paths are **1-based** (XPath convention): `'/body/p[3]'` = third paragraph
- `--index` is **0-based** (array convention): `--index 0` = first position
- **Excel exception**: for `add --type row` and `add --type col`, `--index N` is **1-based** (matches OOXML RowIndex / column letter index). `--index 5` inserts at row 5 / column 5.
- After modifications, verify with `validate` and/or `view issues`
- **When unsure**, run `officecli help <format> <element>` instead of guessing
