When to convert delimiters

US-centric pipelines expect commas. Finance teams in Germany, France, and Scandinavia send semicolons. BI tools sometimes require tabs. Replacing characters globally is wrong: it will split decimal amounts and addresses.

How this converter avoids splitting fields

The file is parsed with the detected delimiter first. Only then is it serialized with the delimiter you choose. Fields that contain the new delimiter, quotes, or line breaks are wrapped in quotes and interior quotes are doubled.

Example

name;amount
"Dupont, Anne";12,50

Converted to comma CSV:

"name","amount"
"Dupont, Anne","12,50"

Limitations

If the source delimiter was detected incorrectly, convert after using the detector or the validator. This tool does not merge or split columns.

FAQ

Will amounts like 12,50 stay intact?

Yes. After the file is parsed with the source delimiter, 12,50 is one field. If you switch the delimiter to comma, that field is quoted.

Can I convert TSV to CSV?

Drop the TSV, choose comma as the output delimiter, and download. Tabs inside fields are preserved.

Do you change encoding?

Download is UTF-8. Use the encoding fixer first if names are already garbled.
