Change CSV Delimiter
Convert CSV separators between comma, semicolon, tab, and pipe
Swap the delimiter of any separated-values file between comma, semicolon, tab, and pipe — in either direction, in one step. Paste the data or upload the file, pick the current and target separators, and download the rewritten file.
The file is parsed as structured data before anything is rewritten, so a value that contains the new delimiter is quoted instead of being split into two fields. That is the failure mode of find-and-replace in a text editor, and the reason this tool exists.
The most common use is regional Excel settings: many European locales expect semicolon-separated files, while most APIs and databases expect commas. You can also choose how the output is quoted — only where needed, around every field, or not at all — to match whatever the receiving system requires.

Frequently Asked Questions
Can I convert semicolon CSV to comma CSV?
Yes. Select Semicolon as the input delimiter and Comma as the output delimiter.
Does this upload my file?
No. The delimiter conversion runs entirely in your browser.
Why not just find-and-replace the delimiter in a text editor?
Find-and-replace also rewrites delimiters that appear inside values. A field like "Smith, John" would be split into two columns. This tool parses the file first, so values containing the new delimiter are quoted and stay intact.
Why does Excel open my CSV in a single column?
Your regional settings probably expect a different separator — many European locales use semicolons instead of commas. Convert the file to the delimiter your locale expects and Excel will split it into columns correctly.
What do the quoting options mean?
Minimal quotes only fields that need them (they contain the delimiter, quotes, or line breaks). All wraps every field in quotes, which some strict importers require. None writes fields bare — only safe when you know no value contains the delimiter.
