About this tool
Keep or remove list items that contain, start or end with a text, match a regular expression, are longer or shorter than a length, or are numbers.
Each item is tested against the chosen rule; regular expressions run in a background task with a time limit.
Example: keep items containing “an” from banana, kiwi, mango → banana, mango.
Length counts visible characters, so an emoji or an accented letter counts as one.
Quick steps
- Paste your text or open a file (or press Try an example).
- Choose the options — the result updates as you type.
- Copy the result or download it as a file.
Everything runs in your browser. Nothing you type is sent to 1CLIK.

No. It is processed on your device in a separate background task that is stopped if it takes too long; nothing is stored or sent.
