What problem does it solve?
Use this skill anytime a spreadsheet file is the primary input or output. This enables automating open, read, edit, or fix tasks on files like .xlsx, .xlsm, .csv, or .tsv, including adding columns, computing formulas, formatting, charting, and data cleaning. It also supports creating a new spreadsheet from scratch or from other data sources and converting between tabular formats. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
