The CSV Formatter cleans and standardises CSV data — normalise whitespace in fields, ensure consistent quoting, change the delimiter from comma to semicolon or tab, and validate that all rows have the same column count. Useful before importing CSV into databases or spreadsheet applications.
Clean and standardise CSV files before import to avoid parsing errors and column mismatches. To convert your CSV to JSON, try the CSV to JSON converter.
