How to Use String Splitter
String Split breaks a block of text into pieces around any delimiter and joins the pieces back with a separator you choose. Everything runs locally in your browser, so your text is never uploaded.
- Paste the text you want to process into the input area.
- In the “Split by:” field, enter the delimiter that separates your data, such as a comma, semicolon, space, or a longer string like “ | ”.
- The text splits instantly into a list — one entry for every occurrence of the delimiter.
- In the “Join with:” field, type the separator used to rejoin the pieces, for example a newline, “-” or “, ”, to reshape the output.
- Copy the joined result from the output area and use it wherever you need it.
Use a multi-character delimiter such as “, ” (comma plus space) to avoid splitting on every single comma inside dense text like CSV.
