About thetoolproject

Useful file tools should be easy to use and easy to trust.

thetoolproject.com makes small, focused tools for the file tasks that interrupt your day. Convert JSON to HTML or Excel, turn a spreadsheet into CSV, and get on with your work.

The tools run in your browser. Your files and pasted data stay on your device during conversion, so you can use the tools without uploading a document or creating an account.

Built in the open

The project is open source on GitHub. You can read the code, suggest a change, or contribute under the repository’s MIT License.

Help make the tools better
