Convert JSON objects to TOML config text. Free, private, runs in your browser.
100% private — your files and text never leave your browser. All processing happens locally on your device.
JSON to TOML writes root objects as TOML key/value pairs, nested objects as tables, arrays as TOML arrays, and arrays of objects as arrays of tables.
TOML has no null value. Convertful reports null fields and skips them instead of inventing an ambiguous representation that could break downstream config loading.
The JSON is parsed and serialized locally with deterministic output. Review generated table names and skipped values before replacing a real project config file.
No. TOML has no null value, so nulls are reported and skipped rather than guessed.
Yes. Nested JSON objects become TOML tables, and arrays of objects become arrays of tables.
Yes. String values are quoted for TOML output.
No. Conversion happens in the browser.
No. Phase 4 keeps bundle impact low with a focused local serializer for common config data.
