What problem does it solve?
This Skill removes the repetitive work of creating, cleaning, editing, formatting, and fixing spreadsheet files so tabular work can be delivered as a polished workbook instead of a manual draft.
Core Features & Use Cases
- Spreadsheet Creation and Conversion: Build new workbooks from scratch or convert between xlsx, xlsm, csv, and tsv formats.
- Editing and Cleanup: Add columns, restructure messy tables, preserve existing templates, and apply professional formatting without breaking workbook conventions.
- Formula-Driven Analysis: Insert formulas, projection logic, and cross-sheet references while keeping calculations dynamic and checking for spreadsheet errors.
- Validation and Recalculation: Recompute formulas with LibreOffice, verify outputs, and catch issues such as broken references or invalid results before delivery.
Quick Start
Use the xlsx skill to open the attached spreadsheet, make the requested edits or analysis, and return a corrected workbook with formulas and formatting preserved.
