Split text into separate lines using a delimiter, or join multiple lines into a single string with a custom separator character.
The Text Separator tool is a versatile utility for anyone who works with structured data or needs to reformat text quickly. Whether you have a comma-separated list that needs to be broken into individual lines, or a list of items on separate lines that you want to combine into a single delimited string, this tool handles both directions with a single click.
Common use cases include converting CSV values into line-by-line lists, preparing data for spreadsheet imports, reformatting log entries, and cleaning up copied content from websites or documents. You can use any character or string as your separator — commas, pipes, semicolons, tabs, or even multi-character delimiters.
The split mode takes your text and breaks it apart wherever the separator appears, placing each segment on its own line. The join mode does the opposite — it takes text that is already on separate lines and merges everything into one line with your chosen separator between each piece.
All processing is performed entirely in your browser. No data is sent to any server, ensuring your content stays private. Paste your text, choose your separator and mode, click the button, and copy your result instantly.
