What Is a CSV Delimiter?
A CSV delimiter is the character used to separate values in a CSV file. Common delimiters include commas, semicolons, pipes, and tabs. Different systems and regions expect different delimiters, which often causes import or formatting issues.
Why Change CSV Delimiters?
You may need to change a CSV delimiter if:
- Excel opens all data in one column
- Your system expects semicolon-separated CSV
- You need pipe or tab-delimited files
- Database imports fail due to delimiter mismatch
- Regional settings use different separators

What is a CSV delimiter?
A delimiter is the character that separates values in a CSV file — most commonly a comma, but sometimes a semicolon, tab, or pipe depending on the software that created the file.
Why would I need to change the CSV delimiter?
Different software expects different delimiters. Excel in Europe uses semicolons by default, while most APIs and databases expect commas. Changing the delimiter fixes import errors.
Will changing the delimiter affect my data?
No. The tool preserves all values including quoted fields. Values containing the new delimiter are automatically wrapped in quotes to keep the file valid.
Is my data safe?
Yes. All processing happens in your browser. Your file is never uploaded to any server.
