How do I know which delimiter a file actually uses?

Open it in a plain text editor — the character separating values on each line (comma, tab, semicolon or pipe) is the delimiter.

Does converting the delimiter change the actual data?

No, only the separator character changes — the values themselves stay exactly the same.

Why do some regions default to semicolons instead of commas?

Locales that use a comma as the decimal separator (like many European countries) use semicolons for CSV delimiters instead, to avoid ambiguity with decimal numbers.

Does CSV Delimiter Converter upload my files to a server?

No. CSV Delimiter Converter runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Not every system that reads "CSV" agrees on the delimiter — some export comma-separated files, others tab-separated, and European locales often default to semicolons since commas are used as decimal points there. Importing a file with the wrong delimiter assumption produces a single garbled column instead of properly separated fields. This tool converts a delimited file between comma, tab, semicolon and pipe formats, so you can match whatever delimiter the destination system actually expects.
