# Why a rule-based cleaner beats ChatGPT for CSV cleanup

ChatGPT can rewrite tables but may invent cells and requires an upload. CleanMySheet applies named, reversible operations with a per-cell reason and a downloadable quality report. Use an LLM only as an optional type hint on samples, never as the row engine.

## Steps

- Try the sample dataset
- Toggle a recipe step off
- Undo with Ctrl+Z
- Compare with a chatbot paste

## When a model still helps

Ambiguous column types on messy headers. Turn Strict off to send ~15 sample values per unsure column to Haiku. Full rows still stay local.
