TextToolbox is a collection of 18 small, focused tools for the text and data you handle every day: counting words, fixing case, cleaning up lists, formatting JSON, encoding strings and generating IDs and passwords.
How it is different
- The tool comes first. Every page opens with the tool ready to use and a live example, so you can start in one second. Explanations come after, for when you need them.
- Nothing is uploaded. Every tool runs in your browser. Text, JSON, CSV and passwords stay on your device — which is why it is safe to paste an API response or a customer list here.
- Results update as you type. No “Submit” buttons, no loading screens.
- It gets the details right. Emoji count as one character, Base64 handles every language, CSV parsing follows the standard, and passwords use a cryptographic random source.
