XLSX Skill

Handle spreadsheet creation and editing with clean formulas, stable structure, and verification-friendly outputs.

When to Use

Use this skill when the user needs .xlsx, .xlsm, .csv, or .tsv data cleaned, analyzed, reshaped, or delivered as a spreadsheet.
Use it for workbook fixes, formula updates, dashboards, and repeatable tabular exports.
Prefer this skill when the spreadsheet file itself is the deliverable, not just an intermediate format.

Workflow

Inspect workbook sheets, headers, formulas, named ranges, charts, and formatting before editing.
Preserve existing workbook conventions unless the user explicitly asks for a redesign.
Use spreadsheet formulas for values that should remain dynamic after handoff.
Keep raw inputs, assumptions, calculations, and outputs clearly separated when building a new workbook.
Save, recalculate, and inspect the result before declaring success.

Guardrails

Do not replace formulas with hardcoded numbers unless the user explicitly asks for static values.
Avoid introducing broken references, hidden circular dependencies, or inconsistent fill patterns across rows and columns.
Keep date, currency, percent, and decimal formats consistent within each sheet.
When cleaning messy data, preserve the original data in a separate sheet or output file when possible.
If required spreadsheet tooling is missing, say what is missing and stop.

Common Tooling

pandas for data loading, cleaning, and reshaping.
openpyxl for workbook formulas, formatting, charts, and sheet-level edits.
libreoffice or another spreadsheet engine for recalculation and visual checks.
