How to use this tool
1. Paste raw CSV into the input panel or upload a .csv file. 2. Review the table preview for correct columns and row counts. 3. Adjust delimiter or header options if your file uses tabs or semicolons. 4. Use Format to tidy quoting and spacing. 5. Copy the cleaned CSV or download it when the preview looks correct.
