How It Works
Validate and debug CSV data against RFC 4180 specifications directly in your browser.
- RFC 4180 Compliance: Detects unclosed quotes, multiline records, and escaping errors.
- Column Uniformity: Flags rows with missing or extra columns compared to headers.
- Data Quality: Identifies duplicate headers, type inconsistencies, and whitespace issues.
- Privacy First: Your files never leave your device. All parsing happens locally.
