Delimiter Splitter & Joiner
Split CSV-style or delimited text into lines, or join lines back with a custom separator.
About this tool
Converting between a delimited string (like comma-separated values) and a plain line-by-line list is a frequent small task when moving data between a spreadsheet, a script, and a text field. This tool does both directions.
How to use it
- Paste your text — either a delimited string or a line-by-line list.
- Set the delimiter character (comma is the default).
- Click split to break it into lines, or join to combine lines back using the delimiter.
Tips
- Splitting trims extra whitespace around each resulting item automatically.
- Any single character or short string can be used as a delimiter, not just commas — try a pipe (|) or semicolon.
- Joining skips empty lines, so blank rows in your list won't leave stray delimiters in the output.
FAQ
Can I use a multi-character delimiter, like '::'?
Yes, the delimiter field accepts any string, not just a single character.
