What problem does it solve?
Enable reliable creation, editing, cleaning, and conversion of spreadsheet files when a spreadsheet is the primary input or deliverable, removing manual errors and ensuring models recalc correctly.
Core Features & Use Cases
- Read, edit, and create spreadsheets: Open and modify .xlsx, .xlsm, .csv, and .tsv files while preserving templates and formatting.
- Formula-first workflows: Insert and preserve Excel formulas (never hardcode calculated results) and use LibreOffice recalculation to populate values.
- Validation and repair: Recalculate formulas, scan for Excel error values (#REF!, #DIV/0!, #NAME?, etc.), validate OOXML structure, and apply fixes for tracked issues.
- Use Case: Convert messy tabular exports into a normalized workbook, add dynamic formulas, recalculate with LibreOffice, and return a validated .xlsx file ready for financial review.
Quick Start
Use the xlsx skill to recalculate formulas and validate the workbook, then return a corrected, error-free .xlsx file.
