Changing a CSV from commas to semicolons or tabs sounds simple, but a naive find-and-replace destroys any value that already contains the delimiter.
This converter parses the CSV first and then re-serializes it with your target delimiter, so a quoted field keeps its commas and the data stays correct.
How to use CSV Delimiter Converter
- Paste your CSV into the left panel.
- Enter the From delimiter and the To delimiter in the two boxes.
- Copy the re-delimited CSV from the right panel or download it.
What you can do with it
- Convert a comma CSV to a semicolon CSV for Excel.
- Switch an export from commas to tabs.
- Prepare a database file with a specific delimiter.
Good to know
Delimiter conversion requires parse then serialize, not a raw replace. For example a cell holding a value with a comma stays quoted when you switch to semicolons, instead of being split apart.
Frequently asked questions
How do I enter a tab as the delimiter?
Type the two characters backslash t in the box; the tool reads that as a tab character for the conversion.
Why not just replace the delimiter?
Because a replace also changes delimiters that appear inside quoted values, corrupting them. Parsing first avoids that.
Is European semicolon CSV supported?
Yes. Set From to comma and To to semicolon to produce the semicolon style many regional spreadsheets expect.
