What is a Change CSV Separator?
CSV files disagree about what separates fields. English-language tools default to commas, German and French Excel versions export semicolons, some legacy systems use pipes or tabs — and importing a file with the wrong delimiter gives you one giant column instead of a table. This tool rewrites a CSV from one delimiter to another, preserving the data and the quoting.
Set the input separator, quote character and comment character to match your source file, then choose the output separator. If fields in the source contain the old separator inside quotes, the parser respects the quotes rather than splitting mid-value — the difference between a correct conversion and corrupted rows. You can also drop empty lines and comment lines during conversion, and optionally quote every output field, choosing the output quote character yourself.
A concrete example: a pipe-separated export from an old inventory system becomes standard comma-separated CSV in one pass, ready for a spreadsheet import wizard that has never heard of pipes. The live table preview shows exactly how the input parses before you commit, which catches delimiter mistakes immediately instead of after the import.
Conversion is done by your browser, locally — the file contents are not uploaded, so there is no risk in processing sales data, customer records or anything else sensitive.
Change CSV Separator Examples

In this example, we change the column separator to the semicolon separator in a CSV file containing data about countries, their populations, and population densities. As you can see, the input CSV file uses the standard commas as separators. After specifying this delimiter in the source CSV options, we set a new CSV delimiter for the output file to a semicolon, resulting in a new CSV file that now uses semicolons ";" in the output. Such CSV files with semicolons are called SSV files (semicolon-separated values files)

In this example, a data scientist working with flowers was given an unusual CSV file that uses the vertical bar symbol as the field separator (such files are called PSV files – pipe-separated values files). To transform the file back to the standard comma-separated values (CSV) file, in the options, she set the input delimiter to "|" and the new delimiter to ",". She also wrapped the output fields in single quotes, enabled the option to remove empty lines from the input, and discarded comment lines starting with the "#" symbol.

Enter the quote character used to quote the CSV output fields.
In this example, we import CSV data with zombie characters from the game Plants vs. Zombies. The data includes zombies names, the level at which they first appear in the game, their health, damage, and speed. The data follows the standard CSV format, with commas serving as field separators. To change the readability of the file, we replace the usual comma delimiter with a slash symbol, creating a slash-separated values file.
