This Skill helps you work with spreadsheet files (.xlsx/.xlsm/.csv/.tsv) end-to-end—opening, fixing, restructuring messy data, updating templates, performing analysis, and producing a correct spreadsheet output.
Core Features & Use Cases
- Spreadsheet-safe updates with guardrails: Uses Excel formulas (not Python hardcoding), enforces zero formula errors, and preserves existing template formatting when editing.
- Messy data cleaning and restructuring: Fixes malformed tables, misplaced headers, and junk rows to produce a valid, usable spreadsheet.
- File conversion and tabular transformation: Converts between tabular formats and generates new spreadsheets from provided tabular data.
