The Comma Separator is a versatile utility for developers, data analysts, and writers. It serves two main purposes: converting a vertical column of text into a single line separated by commas (or any other character), and splitting a delimited string back into a vertical list. It's particularly useful for generating SQL 'IN' clauses, formatting array data for code, or cleaning up data from spreadsheets.
Paste your list or text into the input box. The tool detects the format automatically.
Select "List to Text" to join items or "Text to List" to split them.
Pick your delimiter (comma, pipe, etc.) and choose if you want quotes around items.
The formatted text appears instantly. Click "Copy Result" to use it.
