Frequently Asked Questions
What does it convert?
A JSON object into TOML, with simple values as key-value pairs and nested objects as TOML tables.
Does the top level need to be an object?
Yes. TOML starts from a table, so a bare array or value is reported as not convertible at the top level.
How are arrays handled?
Arrays of simple values become inline TOML arrays in square brackets.
Is my data sent anywhere?
No. The conversion runs entirely in your browser, so your JSON never leaves the tab.
Is it free?
Yes. Every tool here is free to use with no sign up.
