Frequently Asked Questions

There is no universal CSV standard. Excel in European countries defaults to semicolons because commas are used as decimal separators. Databases often export with tabs. Legacy systems may use pipes. The delimiter depends on the software that created the file.

Yes. Select "Custom…" from the delimiter dropdown and type any single character. Common choices include pipe (|), tilde (~), or caret (^) for data that contains commas and semicolons.

No. The tool uses PHP fgetcsv() which correctly handles quoted fields containing the delimiter character. For example, a field value of "Smith, John" remains intact when converted from comma to semicolon delimiter.

The tool will detect this and show an error asking you to choose a different target delimiter. This prevents creating an invalid file.

Yes. Only the delimiter character between fields is changed. All data values, row count, and column structure remain identical.

Auto-detect analyses the first few lines of your file and counts occurrences of common delimiters (comma, semicolon, tab, pipe) outside quoted fields. The delimiter with the highest consistent count is selected automatically.
