Spreadsheets

Use this skill for XLSX, CSV, TSV, formulas, charts, and tabular reports.

Workflow:

• Inspect columns, row count, encodings, and missing values.
• Preserve source files; write cleaned outputs separately.
• Make transformations explicit and repeatable.
• Validate totals, formulas, date parsing, and header names.
• Prefer CSV for simple outputs when spreadsheet libraries are unavailable.
