fastxlsx

name	fastxlsx
description	Edit and validate `.xlsx` workbooks through the `fastxlsx` CLI. Use for config-table updates, structured-sheet edits, sheet management, style changes, and roundtrip-safe workbook modifications instead of touching workbook XML directly.

FastXLSX

This is the Cursor skill entrypoint for this repository.

Keep this file short. Detailed workflow rules live in WORKFLOW.md inside this Cursor skill directory.

When To Use

• Inspecting .xlsx workbooks before editing
• Single-cell edits and style updates
• config-table updates
• Structured table edits and profile-based workflows
• Deterministic multi-step edits through apply --ops
• Roundtrip validation after workbook changes

Command Entry

For .xlsx tasks in Cursor, read this skill's workflow first:

.cursor/skills/fastxlsx/WORKFLOW.md

Use the first available CLI entry:

fastxlsx <subcommand> ...

If fastxlsx is not on PATH but the package is available:

npx fastxlsx <subcommand> ...

Only when working inside the fastxlsx repository root:

npm run cli -- <subcommand> ...

The workflow document uses fastxlsx as shorthand for whichever entry is available.
