TOML ↔ JSON converter

Paste a .toml document — get pretty-printed JSON, or paste a JSON object to get canonical smol-toml@1 output (TOML 1.0.0 spec). Runs locally in your browser — no server round-trip.

Direction

Paste a TOML document — get pretty-printed JSON. Dates become ISO strings (JSON has no date type); other types round-trip cleanly.

TOML input

TOML 1.0.0 — bare or quoted keys, tables, inline tables, arrays, dates, multi-line strings.

Output

Paste a TOML document above to see the converted output here.
