TOML to JSON

TOML → JSON · tables → nested objects

Paste TOML, get JSON. Tables become nested objects; array-of-tables become arrays of objects. Reverse direction at JSON → TOML. Useful for piping TOML configs into JSON-only tools.

Paste TOML.

How to convert TOML to JSON

  1. Paste in either panel.
  2. The opposite panel updates live. Swap to flip direction.
  3. TOML output respects the original key order. Nested objects become tables ([parent.child]); arrays of objects become array-of-tables ([[items]]).
  4. Copy or Download.

FAQ

Does it support TOML dates and datetimes?

Yes — they're serialized as ISO 8601 strings in the JSON output. Re-parsing in your downstream code may need a date-aware deserializer.

What about TOML 1.0 vs 0.x?

TOML 1.0 is the default. Most 0.x docs parse fine, but exotic 0.x corners (inline-table whitespace, dotted-key ordering) may need cleanup.

Will it work offline?

Yes.
