About CSV Preflight
CSV Preflight is a browser and one-file Node.js CLI for checking CSV structure without uploading data. The free core detects encoding problems, delimiter mistakes, duplicate or empty headers, uneven rows, and duplicate records, then downloads normalized output and an issue report. An optional paid Pro edition adds batch processing, named import profiles, ZIP output, and JSON reports.
Key features
- ✓ Runs locally in the browser or as a one-file Node.js CLI
- ✓ Checks encoding, delimiters, headers, row widths, and duplicates
- ✓ Downloads normalized CSV and a clear issue report
