clean-data-xls

Clean up messy spreadsheet data — trim whitespace, fix inconsistent casing, convert numbers-stored-as-text, standardize dates, remove duplicates, and flag mixed-type columns. Use when data is messy, inconsistent, or needs prep before analysis. Triggers on "clean this data", "clean up this sheet", "normalize this data", "fix formatting", "dedupe", "standardize this column", "this data is messy".

This skill ships only metadata — no inline instructions. See the source repo for details.

Install this skill

One command (all agents)

Runs the npx skills CLI which auto-detects every AI coding agent you have installed (Claude Code, Cursor, Codex, OpenCode, Windsurf, Copilot, and 51 more).

Manual install (no CLI)

Prefer to skip the CLI? Clone the repo and drop the skill folder into your agent's skills directory.

git clone https://github.com/anthropics/financial-services-plugins.git

cp -r financial-services-plugins ~/.claude/skills/

For other agents, replace ~/.claude/skills/ with their skill directory — see the full list.

Use it

Once installed, ask your agent to "use the clean-data-xls skill" or describe what you want (e.g. "Clean up messy spreadsheet data — trim whitespace, fix inconsistent casing, conv"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.
