Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file; create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Also trigger for cleaning or restructuring messy tabular data. The deliverable must be a spreadsheet file.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Important:** All `scripts/` paths are relative to this skill directory.
> Use `run_skill_script` tool to execute scripts, or run with: `cd {this_skill_dir} && python scripts/...`
# Requirements for Outputs
## All Excel files
### Professional Font
- Use a consistent, professional font (e.g., Arial, Times New Roman) unless otherwise instructed
### Zero Formula Errors
- Every Excel model MUST be delivered with ZERO formula errors (#REF!, #DIV/0!, #VALUE!, #N/A, #NAME?)
### Preserve Existing Templates
- Study and EXACTLY match existing format, style, and conventions when modifying files
- Existing template conventions ALWAYS override these guidelines
## Financial Models
### Color Coding Standards
- **Blue text (0,0,255)**: Hardcoded inputs
- **Black text (0,0,0)**: ALL formulas and calculations
- **Green text (0,128,0)**: Links from other worksheets
- **Red text (255,0,0)**: External links to other files
- **Yellow background (255,255,0)**: Key assumptions needing attention
### Number Formatting Standards
- **Years**: Format as text strings ("2024" not "2,024")
- **Currency**: Use $#,##0 format; specify units in headers ("Revenue ($mm)")

How to install
mdr add mateaix/mateclaw/xlsx@sha256:43eb2c678e242d4eThe line at the top of this page pins the label git:20260404.579d601, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
