Frequently asked questions
Is my JSON data sent to a server ?
No. The conversion happens entirely in your browser. Nothing is uploaded or stored online.
Does TOML support nested structures ?
Yes. Nested objects become TOML tables and lists become arrays. The tool preserves the hierarchy of your original JSON.
What happens if my JSON is invalid ?
The tool reports the parsing error. Check your commas, braces and quotes before running the conversion again.
Can I convert arrays of objects ?
Yes. Arrays of objects are turned into TOML arrays of tables using the double bracket notation.
