Excel spreadsheets (Anthropic)
Creates, edits and analyses Excel and CSV files with working formulas, formatting and charts, and tidies messy tables into proper spreadsheets. Built-in scripts recalculate formulas and check for errors before the file is handed back.
When to use it
Whenever the end result is a spreadsheet, such as a budget, price list, sales tracker or cleaned up export.
What it can access
- Runs code
- Reads or writes files
Before you enable it: Runs bundled Python scripts, and LibreOffice for recalculation, on your files inside the agent's sandbox. It is source-available under Anthropic's terms, which restrict copying or adapting it outside Anthropic's services.

How to install
This skill uses the open Agent Skills format (a folder with a SKILL.md file), so the same file works in several agents.
- Claude Code: put the folder in ~/.claude/skills/
- Other agents that read SKILL.md: follow that agent's skills docs.
Public skill hubs have carried malicious skills. Wize reads every skill before installing it and sets it up so a person approves anything it sends.
