SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires openpyxl, and includes scripts (resource) components.

What problem does it solve?

Use this skill to rapidly manipulate spreadsheet files (xlsx/xlsm/csv/tsv) — reading, editing, formatting, computing formulas, cleaning messy data, converting between tabular formats, and exporting the result as a spreadsheet file. It triggers when a user references a spreadsheet by name or path and requires the deliverable to be a spreadsheet.

Core Features & Use Cases

  • Open, read, edit, and fix .xlsx, .xlsm, .csv, or .tsv files.
  • Compute formulas, apply formatting, restructure data, and convert between tabular formats.
  • Example use case: clean a messy dataset, add computed columns, and export a polished sheet for sharing.

Quick Start

Open your input spreadsheet, apply the requested edits (add columns, compute formulas, format, and clean data), and export the result as a new .xlsx file.

FAQPage Schema
How do I automate spreadsheet data cleaning and formatting for xlsx files?▼

Automate spreadsheet data cleaning and formatting by reading .xlsx, .xlsm, .csv, or .tsv inputs, applying restructuring rules, and exporting the result as a single polished spreadsheet file.

Can I compute formulas and convert CSV to xlsx while preserving formatting?▼

Yes, you can compute formulas and convert CSV to xlsx while applying formatting. The process reads tabular inputs, calculates formulas, and exports a single spreadsheet file preserving the applied formatting.

Does openpyxl support converting between xlsx, xlsm, csv, and tsv formats?▼

Yes, openpyxl supports converting between xlsx, xlsm, csv, and tsv formats. The skill uses this dependency to open, read, edit, and restructure tabular data before exporting the final result as a spreadsheet file.

What is the best way to fix messy data and add computed columns in a spreadsheet?▼

The best way to fix messy data and add computed columns is to open the input spreadsheet, apply data cleaning rules, compute new formula-based columns, and export the restructured data as a new .xlsx file.

Are there limitations when exporting spreadsheet files with formulas and formatting?▼

A key limitation is that exports must produce a single spreadsheet file. The process preserves formulas and formatting during export, but the deliverable is strictly limited to one spreadsheet file per task.
