  extended_description: |
    The jasp_ext extension reads [JASP](https://www.jasp.org/) project files (`.jasp`) directly as SQL tables.

    A `.jasp` file is a ZIP archive containing `internal.sqlite` (the real data), `analyses.json`
    (analysis registry) and `resources/N/jaspResults.json` (per-analysis results). Data lives in
    `DataSet` / `DataSet_N` tables where every logical column is stored as a pair of physical
    columns (`Column_{id}_DBL` value, `Column_{id}_INT` categorical code). The extension maps
    these back to logical typed columns:

    | JASP column type | DuckDB type | source |
    |---|---|---|
    | scale | DOUBLE | `_DBL` REAL value, `nan` → NULL |
    | ordinal | DOUBLE | `_DBL` code |
    | nominal | VARCHAR | `Labels[_INT]` |
    | nominalText | VARCHAR | `_DBL` text value |

    **Table functions:**

    | function | description |
    |---|---|
    | `read_jasp(path)` | all data rows (typed), from the default DataSet |
    | `read_jasp(path, dataset)` | a specific `DataSet_N` |
    | `read_jasp_columns(path [, dataset])` | column metadata (id, name, columnType) |
    | `read_jasp_analyses(path)` | one row per registered analysis |

    **Example:**

    ```sql
    SELECT * FROM read_jasp('/path/to/project.jasp');
    SELECT * FROM read_jasp_columns('/path/to/project.jasp');
    SELECT * FROM read_jasp_analyses('/path/to/project.jasp');
    ```

    **Install:** `INSTALL jasp_ext FROM community;`
