JSON to TOML

A JSON object → TOML: scalars and arrays of scalars inline, nested objects as [tables], arrays of objects as [[tables]]. TOML has no null, so null values are dropped — and listed in the note. Round-trips with TOML to JSON.

How to use JSON to TOML

Objects → [tables], arrays of objects → [[tables]], scalars inline; nulls dropped and listed.

  1. Prepare your input

    Paste a JSON object.

  2. Use the workspace

    Review tables, arrays and the note about dropped nulls.

  3. Check your result

    Download TOML and test it with your configuration reader.

Know the limits

TOML has no null value. Nulls are omitted, so a round trip can lose those properties.
