ToolsSoup's CSV Delimiter Converter is a free online tool that changes the delimiter of a CSV file — for example from commas to semicolons or tabs. It re-parses your data and rewrites it with the new separator, adding or removing quotes as needed so the result is always valid. Everything runs in your browser — nothing is uploaded.

      

        
What is a CSV delimiter?

        
A delimiter is the character that separates the values in each row of a CSV file. Comma is the most common, but many tools and regions use a semicolon — especially Excel in countries where the comma is the decimal separator — or a tab, which produces a TSV file. Converting between delimiters lets a file created by one program open correctly in another without scrambled columns.

        
      

      

        
How to change a CSV delimiter online

        
Converting a delimiter with ToolsSoup takes just a few seconds:

        
  1. Paste your CSV into the input box.
  2. Choose the From delimiter your file currently uses and the To delimiter you want.
  3. Click Convert, then copy the re-delimited CSV.

      

      

        
How are quotes handled during conversion?

        
The converter fully parses your CSV first, so quoted fields are understood correctly. When it writes the output, it adds quotes only where the new delimiter requires them — a value that needed quotes because it contained a comma may no longer need them once the delimiter is a semicolon, and vice versa. Quotes inside a value are escaped by doubling, exactly as the CSV standard expects.

Why would I change a CSV delimiter?

          
Different programs and regions expect different separators. Excel in many European locales uses semicolons, while tab-separated files (TSV) are common in data pipelines. Converting the delimiter makes a file open with the columns lined up correctly.

        

        

          
Does it handle quoted fields and commas inside values?

          
Yes. The CSV is fully parsed before being rewritten, so commas inside quoted fields are preserved and re-quoted only if the new delimiter needs it.

        

        

          
Can it create a TSV file?

          
Yes. Choose Tab as the To delimiter to turn your CSV into a tab-separated (TSV) file.

        

        

          
Is my data safe?

          
Absolutely. All conversion happens locally in your browser using JavaScript, so your CSV is never sent to or stored on any server.
