FAQ
Everything you need to know about the CSV Repair.
What problems can be repaired?
Mismatched quotes, inconsistent delimiters, Windows/Mac line endings, non-UTF-8 encoding.
Is repair always successful?
Common issues are reliably fixed. Severely corrupted files may need manual intervention.
Is my file uploaded?
No. Everything runs locally in your browser.
File size limit?
Process files up to the browser memory limit.
Can it fix wrong delimiters?
Yes — the tool auto-detects the actual delimiter and converts to comma-separated.
What delimiters does it support?
CSV Repair supports comma (,), semicolon (;), tab (\t), and pipe (|) delimiters. In Auto mode it detects the delimiter from the first few rows. If your file uses a non-standard delimiter, switch to Manual and specify it explicitly. Semicolon-delimited files are common in European software (SAP, DATEV).
Will the tool change my actual data values?
No. The repair only fixes structural problems — quote escaping, row alignment, and encoding — without altering the content of any field. Your product names, prices, dates, and IDs remain exactly as they were. The output is a structurally valid CSV that any parser can read without errors.
