Converting a pasted list into a format another tool accepts.

String Splitter: limits and things worth knowing

Choose the delimiter deliberately: splitting on a comma breaks any value that legitimately contains one, which is exactly why CSV quotes such fields.
Trailing delimiters produce an empty final entry, which is usually not wanted and easy to miss.
Whitespace around items is preserved unless trimmed, and leading spaces are a common cause of failed lookups downstream.
Multi-character delimiters are useful when single characters appear inside the data.

Is it private and secure?

Your privacy is built in. String Splitter runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
