XLSX Skill (Anthropic Official Source)

Source: https://github.com/anthropics/skills/tree/main/skills/xlsx

Use this skill for spreadsheet-centric workflows.

When running inside sciClaw, prefer the built-in typed spreadsheet tools over ad-hoc shell calls:

• xlsx_review_read
• xlsx_review_diff
• xlsx_review_apply

Use raw xlsx-review CLI only for advanced modes not covered by those typed tools, such as --create, --textconv, or --git-setup.

Typical Triggers

• "update this Excel file"
• "create a spreadsheet model"
• "clean this CSV/TSV and output xlsx"
• "add formulas/charts/formatting to workbook"

Working Rules

1. Use formulas in the sheet instead of hardcoded computed values.
2. Preserve existing workbook conventions when editing templates.
3. Validate output for formula errors (#REF!, #DIV/0!, #VALUE!, etc.).
4. Keep transformation provenance for publication-quality reproducibility.

Quick Commands

import pandas as pd
df = pd.read_excel("input.xlsx")
df.to_excel("output.xlsx", index=False)
