  • Your input can use common delimiters like commas, pipes (|), semicolons (;), or tabs.
  • Use the Options box to define how the conversion works:
    • Current delimiter: Select the symbol currently used to separate fields in your input.
    • New delimiter: Select the symbol you want to use as the new delimiter.
    • Trim fields: Removes leading/trailing whitespace from each field.
    • Quote values: Wraps all values in double quotes, escaping any embedded quotes.
  • The result updates live in the Converted Output box.
  • A Total characters counter appears beneath the output so you can track the result size.
  • Click Copy Output to copy the converted text to your clipboard.
  • Use Export to File to download the result as a .csv file.
  • Click Clear All to reset the form, input/output areas, file label, and all options.

What Change CSV Delimiter can do:

Change CSV Delimiter transforms structured text by switching out one field separator for another without breaking your data. Whether you’re moving from pipe to comma, tab to semicolon, or preparing data for a system that expects a specific delimiter, this tool makes it easy. With built-in trimming and quoting options, it cleans and formats your file while you watch. It’s fast, flexible, and runs entirely in your browser, so your data never leaves your device.

Example:

Before (pipe-delimited):

name|age|city
Alice|30|New York
Bob|25|Los Angeles

After (converted to comma):

name,age,city
Alice,30,New York
Bob,25,Los Angeles

Common Use Cases:

Use this tool when preparing CSVs for systems that don’t accept your current delimiter, such as importing pipe-delimited files into spreadsheet apps, changing semicolons to commas for SQL tools, or reformatting log files. It’s quick, flexible, and works without any installs or scripts.

Useful Tools & Suggestions:

Before switching delimiters, run Validate CSV to catch any formatting issues that could break with the change. And after adjusting, Convert CSV to TSV or Convert CSV to SSV are handy if you’re targeting those specific formats.
