String Split
Split text by a separator and join with custom delimiter. Runs entirely in your browser.
How does the String Split tool work?
The tool splits your input text at every occurrence of the separator you provide, producing a list of segments that you can rejoin with a custom delimiter. Processing happens locally in your browser—no data is uploaded.
Can I use regular expressions as the separator?
Not currently. The tool accepts plain-text separators (single characters or strings). Enter the exact character(s) or string to split by.
What is the join delimiter and how do I use it?
The join delimiter is the string used to reassemble split segments. For example, split by a comma and set the join delimiter to a newline to convert CSV values into separate lines.
Is my data private and secure?
Yes. All splitting and joining are performed locally in your browser; nothing is sent to any server, keeping your data private.
