Detects the delimiter, flags rows with the wrong number of columns, and actively cleans the file — trimming whitespace, dropping ragged rows, and re-quoting fields consistently.
Messy exports (extra whitespace, inconsistent quoting, occasional broken rows) are a constant, unglamorous pain point — this fixes the common cases in one pass.
Paste CSV/TSV text or upload a file. The delimiter and any ragged rows are flagged immediately; click Clean & Download for a fixed copy.
Uses a proper quote-aware parser, so embedded commas/quotes/newlines inside quoted fields are handled correctly. Encoding is assumed to be UTF-8.
