How it works
Four steps. Under a minute. No account needed.
Step 1
Upload
Drop your broken CSV file. It stays in your browser — never uploaded to a server.
Step 2
Diagnose
Auto-detects encoding (UTF-8, Windows-1252, etc.) and delimiter (comma, tab, semicolon, pipe).
Step 3
Preview
See your data in a clean table. Inconsistent rows and parse warnings are flagged.
Step 4
Export
Download a clean UTF-8 CSV with proper escaping and normalized line endings.
