  title: Microsoft Excel Write Through a Named Range
  summary: Resolve a workbook's named items, read the range a name points at, and write values through it.
  description: >-
    Hard-coding "A1:D3" into an integration means the integration breaks the
    first time somebody inserts a row. Named items are Excel's answer to that: a
    stable name the workbook owner controls, pointing at an address that can
    move underneath it. This flow resolves the workbook's named items, reads the
    range the target name currently resolves to, and writes values through that
    resolved address, so the contract between the caller and the workbook is the
    name rather than a coordinate. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI.

  summary: Write into a workbook range addressed by its defined name rather than a fixed coordinate.
  description: >-
    Lists the workbook's named items, reads the range the first named item
    resolves to, writes new values into that range, and verifies the write.
  inputs:
    type: object
    required:
    - itemId
    - worksheetIdOrName
    - address
    - values
    properties:
      itemId:
        type: string
        description: The drive item id of the workbook file.
      worksheetIdOrName:
        type: string
        description: The worksheet the named range lives on.
      address:
        type: string
        description: >-
          The A1-notation address the named item resolves to on that worksheet,
          confirmed against the named item list this flow reads (e.g. "A1:D3").
      values:
        type: array
        description: A two-dimensional array of values shaped to the named range.
        items:
          type: array
          items: {}
  steps:
  - stepId: openSession
    description: Open a persisting session so values written through the named range are saved.
    operationId: createWorkbookSession
    parameters:
    - name: item-id
      in: path
      value: $inputs.itemId
    requestBody:
      contentType: application/json
      payload:
        persistChanges: true
    successCriteria:
    - condition: $statusCode == 201
    outputs:
      sessionId: $response.body#/id
  - stepId: resolveNamedItems
    description: >-
      List the workbook's named items. Each carries the formula or range
      reference it points at, which is what the caller checks the target address
      against before writing anything.
    operationId: listNamedItems
    parameters:
    - name: item-id
      in: path
      value: $inputs.itemId
    - name: workbook-session-id
      in: header
      value: $steps.openSession.outputs.sessionId
    successCriteria:
    - condition: $statusCode == 200
    - context: $response.body
      condition: $.value.length > 0
      type: jsonpath
    outputs:
      namedItems: $response.body#/value
      firstNamedItemName: $response.body#/value/0/name
      firstNamedItemValue: $response.body#/value/0/value
  - stepId: readNamedRange
    description: >-
      Read the range the name resolves to, capturing its current values and
      dimensions so the caller can confirm the payload matches the shape.
    operationId: getRange
    parameters:
    - name: item-id
      in: path
      value: $inputs.itemId
    - name: worksheet-id-or-name
      in: path
      value: $inputs.worksheetIdOrName
    - name: address
      in: path
      value: $inputs.address
    - name: workbook-session-id
      in: header
      value: $steps.openSession.outputs.sessionId
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      priorValues: $response.body#/values
      rowCount: $response.body#/rowCount
      columnCount: $response.body#/columnCount
  - stepId: writeNamedRange
    description: >-
      Write the values through the resolved address. Because the address came
      from the named item, the integration keeps working when the owner moves
      the data and updates the name.
    operationId: updateRange
    parameters:
    - name: item-id
      in: path
      value: $inputs.itemId
    - name: worksheet-id-or-name
      in: path
      value: $inputs.worksheetIdOrName
    - name: address
      in: path
      value: $inputs.address
    - name: workbook-session-id
      in: header
      value: $steps.openSession.outputs.sessionId
    requestBody:
      contentType: application/json
      payload:
        values: $inputs.values
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      writtenAddress: $response.body#/address
      writtenValues: $response.body#/values
  outputs:
    namedItems: $steps.resolveNamedItems.outputs.namedItems
    resolvedName: $steps.resolveNamedItems.outputs.firstNamedItemName
    priorValues: $steps.readNamedRange.outputs.priorValues
    writtenAddress: $steps.writeNamedRange.outputs.writtenAddress
