Repair and export
String values, including leading zeros, stay as text during inspection
How to use
Paste or load CSV, inspect the detected structure, choose explicit repair options, preview rows, and export UTF-8 CSV or continue to Spreadsheet Studio or JSON.
Example
Open a semicolon CSV with a quoted name such as "Smith, John", then export comma CSV with a UTF-8 BOM for Excel.
Limitations
Automatic delimiter detection can be ambiguous for short files. Repairs preserve cell strings but cannot infer the intended meaning of malformed data.
