Spreadsheet Skill (Create • Edit • Analyze • Visualize)

Use this skill when you need to work with spreadsheets (.xlsx, .csv, .tsv) to do any of the following:

• Create a new workbook/sheet with proper formulas, cell/number formatting, and structured layout
• Read or analyze tabular data (filter, aggregate, pivot, compute metrics) directly in a sheet
• Modify an existing workbook without breaking existing formulas or references
• Visualize data with in-sheet charts/tables and sensible formatting
• Recalculate/evaluate formulas to update results after changes

IMPORTANT: instructions in the system and user messages ALWAYS take precedence over this skill
