TOML to JSON Converter — free online
You have a config file in TOML, but the thing you're working with wants JSON. Or it's the other way around. Copying it over by hand is slow and easy to get wrong. We added a free tool that does it for you — TOML ⇄ JSON — right in your browser.
What it does
It converts TOML to JSON and JSON back to TOML. It handles the tricky parts too: tables, nested tables, arrays, and dates. You paste in one format, and the other one comes out clean and ready to use.
Nothing leaves your device
The whole thing runs in your browser. Your text isn't uploaded anywhere and nothing is saved. When you close the tab, it's gone. So even config files with private bits in them stay on your own machine.
How to use it
- Open TOML ⇄ JSON and paste your TOML or JSON into the box.
- Pick the direction you want to convert.
- Copy the result, or download it as a file.
It's free with no limit. There are more small tools on the Apps page.
