# Export Flow

This skill assumes an upstream structured artifact already exists.

## Input Contract

Required keys:

- `sheet_name`
- `columns`
- `rows`

Recommended keys:

- `source`
- `partial`
- `notes`

## Export Sequence

1. Confirm the task is export-only.
2. Validate that `sheet_name` is non-empty.
3. Validate that `columns` is a non-empty list.
4. Validate that `rows` is a list of row arrays aligned to `columns`.
5. Call `openxml_office` with:
   - template path
   - output `.xlsx` path
   - `sheet_name`
   - `columns`
   - `rows`
6. Return the generated workbook path and any partial-data warning.

## Output Contract

Return:

- output file path
- sheet name
- row count
- whether the source artifact was partial
