CSV delimiter fixer

CSV files do not always use commas. Some exports use semicolons, tabs, or pipes, and the wrong delimiter setting can make a valid file look completely broken. CSVDoctor lets you override delimiter detection and repair structure with the correct parser mode.

How delimiter problems show up

If a semicolon-delimited file is parsed as comma-delimited, every row may appear to have just one column. The opposite problem can create row length mismatches when commas inside text are mistaken for separators.

Examples of CSV errors

id;name;city
1;Alice;Berlin
2;Bob;Paris
3;"Carla;West";Rome

This file uses semicolons, not commas. If the parser assumes commas, the rows will not be split correctly and the quoted semicolon example becomes especially misleading.

When manual delimiter selection helps

Auto-detection works well for most files, but it can be confused by very short data or inconsistent exports. A manual delimiter selector gives you a reliable fallback and helps confirm whether the structural issues are real or just a parsing-mode mismatch.

Use the delimiter override in CSVDoctor

Open CSVDoctor, upload the file, and choose comma, semicolon, tab, or pipe from the delimiter control. The preview table updates with the parsed rows so you can verify the columns immediately.
