What stays local
- CSV parsing
- Full audit findings
- Safe cleanup controls and cleaned-data preview
- Preparation of download files in the browser
CommaLint does not require an account and does not store your spreadsheet contents on CommaLint servers.
What leaves the browser
If you buy and activate a license, CommaLint contacts Lemon Squeezy for activation, validation, and deactivation. Those requests use your license key and browser activation identity—not your CSV rows or columns.
This is a practical privacy design for a static tool, not an enterprise compliance certification.
Try before you pay
Audit and preview are free. When you want the cleaned CSV and HTML audit report downloads, unlock them with a $12 one-time CommaLint v1 Lifetime license (up to 3 browser activations, no subscription).
