What XLSX does

XLSX opens, edits, creates, and analyzes spreadsheet files like .xlsx, .csv, and .tsv, using openpyxl and pandas to handle formulas, formatting, and data cleaning. Use it when the deliverable is a spreadsheet file rather than a report or script.

XLSX is cataloged under Data on DirSkills. XLSX comes from a repository tagged ai-agents, ai-tools, claude-ai, claude-code and claude-code-plugin.

README

Excerpt

XLSX creation, editing, and analysis

Task	Approach
Create or edit with formulas/formatting	`openpyxl` — see gotchas below
Bulk data in or out	`pandas` (`read_excel`, `to_excel`)
Quick look at a sheet	`markitdown file.xlsx` — `## SheetName` per sheet; reads `.xlsm` too. No cell coordinates, so don't plan edits from it
Read a model (formulas and values)	two `load_workbook` passes — see gotchas

openpyxl, pandas, and markitdown are preinstalled — do not run pip install first; write the script and import directly. Only if an import fails (or the markitdown command is missing): pip install the missing package.

Script paths below are relative to this skill's directory.
