What problem does it solve?
This Skill eliminates manual Excel tedium by letting you inspect worksheets, apply targeted cell edits, and generate new workbooks from a simple JSON spec without accidentally breaking formulas or types.
Core Features & Use Cases
- Workbook inspection for LLM workflows: Export sheet structure and cell data types (including formulas as expressions) to JSON so you can reason over tabular content.
- Deterministic in-place edits: Apply structured operations to existing
.xlsx files (set cells, rename sheets, merge ranges) while preserving types and supporting formula writes.
- Create-from-scratch via spec: Build a new workbook from rows plus optional merged ranges and freeze panes.
- Use case: Turn a quarterly revenue plan into an updated workbook by inspecting the existing template, editing only the target cells, and adding computed formulas safely.
Quick Start
Use the xlsx skill to inspect the workbook template at /path/to/book.xlsx and return its sheets, rows, merged ranges, and cell types as JSON.
