Xlsx
Official/About Xlsx
This skill handles any task where a spreadsheet file is the main input or output. It lets the assistant open, read, edit, and fix existing .xlsx, .xlsm, .xltx, .csv, or .tsv files, create new workbooks from scratch or from other data, convert between tabular formats, and clean up messy files with misplaced headers or malformed rows.
The result is always a proper spreadsheet file, built with live formulas rather than hardcoded numbers, professional formatting, and no formula errors.
