Frequently Asked Questions

In many European countries, the comma is used as the decimal separator (e.g. 19,99 €). Using commas as column separators in CSV files causes column splitting errors, so semicolons (;) are used instead.

The tool adheres to RFC 4180: if a cell contains the target delimiter, it will be wrapped in double quotes (e.g. '123 Main St; Apt 4' becomes '"123 Main St; Apt 4"').

Yes! Simply choose 'Tab (\t) [TSV]' as the target delimiter, and you will get clean, standard Tab-Separated Values.
