What problem does it solve?
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file 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.
Core Features & Use Cases
- Open, read, edit, and fix common spreadsheet formats including XLSX, XLSM, CSV, and TSV
- Apply transformations: add columns, compute formulas, format cells, and adjust charts
- Convert between tabular formats and consolidate messy data into clean spreadsheets
- Use Case: Normalize a messy CSV into a clean XLSX with consistent headers, then export to CSV or XLSX for reporting
Quick Start
Open a spreadsheet, apply a simple transformation (such as adding a column or computing a formula), and save the result as a new spreadsheet file.
