What problem does it solve?
This Skill removes the tedium and risk of manually cleaning spreadsheet data, repairing broken workbooks, and converting tabular files into the right Excel format for downstream use.
Core Features & Use Cases
- Create and edit spreadsheets from scratch or from messy tabular inputs (e.g., adding columns, restructuring headers, cleaning junk rows, fixing malformed data).
- Convert between spreadsheet tabular formats such as .csv and .tsv into .xlsx/.xlsm workflows and vice versa.
- Ensure reliability for deliverables by requiring a spreadsheet output and (when formulas are used) running LibreOffice-based recalculation with error scanning for #REF!, #DIV/0!, #VALUE!, #NAME?, and similar issues.
Quick Start
Use the xlsx skill to repair formulas and restructure the attached spreadsheet so it becomes a valid .xlsx with zero Excel formula errors.
