JSON to TOML

Convert a flat or one-level-nested JSON object into TOML — nested objects become [table] blocks, top-level scalar values become key = value lines, strings are quoted.

How to Use JSON to TOML
  1. 1Paste your JSON object (objects become [table] blocks)
  2. 2The TOML output is generated automatically
  3. 3Copy the result
Frequently Asked Questions

Generating TOML from a known, controlled JSON shape (basic key-value pairs, one level of nesting) is a much narrower, safer problem than parsing arbitrary TOML written by hand, which is why generation is handled here while parsing (toml-to-json) is deliberately declined in favor of a real library.

One level — a top-level key with an object value becomes a [table] block; deeper nesting isn't handled.

Yes — string values are wrapped in double quotes per TOML syntax, while numbers and booleans are written as-is.

No — the conversion happens entirely in your browser.
