What problem does it solve?
This Skill helps you open, repair, and transform spreadsheet files so your tabular data is accurate, usable, and error-free without manual spreadsheet-by-spreadsheet work.
Core Features & Use Cases
- Create or edit spreadsheets (XLSX/XLSM/CSV/TSV): Build new workbooks from scratch, convert tabular inputs, and restructure data into proper spreadsheet layouts.
- Clean messy or malformed data: Fix issues like misplaced headers, malformed rows, junk data, and other structural problems that prevent analysis.
- Convert and output tabular files: Convert between tabular file formats and ensure the final deliverable is a spreadsheet file.
Quick Start
Use the xlsx skill any time the spreadsheet file you want to modify or produce is the primary input or output, and ask it to generate the corrected spreadsheet file from the attached data (for example: "Clean the messy .csv and output a corrected .xlsx with properly typed columns and no Excel errors.").
