JSON to TOML Converter Online
Runs 100% in your browser — your files never leave your device.
TOML reads better than JSON for human-edited config, and tools like Cargo and Hugo expect it. Paste JSON (comments and trailing commas allowed) and get TOML with proper tables and typed values out. Nested objects become TOML tables automatically; anything TOML cannot express is flagged.
How it works
- 1
Paste your JSON
Lenient parsing accepts comments and trailing commas.
- 2
Read the TOML
The output updates live as you type.
- 3
Copy the result
One click copies the TOML into your config file.
