About String Utilities
Small string chores come up constantly: reversing text, measuring its length, repeating a phrase, pulling links or email addresses out of a block of text, or collapsing messy whitespace. These are trivial in code but tedious to do by hand.
This toolbox bundles those operations and runs them in your browser, so you can paste text, apply an operation, and copy the result without writing a script or sending the text to a server.
Common use cases
- Extracting all URLs or email addresses from a document.
- Cleaning extra spaces and blank lines from pasted text.
- Checking the length of a string.
- Repeating or reversing text for testing.
Frequently asked questions
- How accurate is URL and email extraction?
- It uses pattern matching, which handles typical cases but may miss unusual formats or include trailing punctuation. Review the output.
- Does the length count characters or bytes?
- Length is measured in characters. Multi-byte characters such as emoji may occupy more bytes when stored.
- Is the text sent anywhere?
- No. It is processed in your browser.
