TOML to JSON

This page does not parse TOML — the format's full grammar (dotted keys, inline tables, arrays of tables, typed dates) needs a real TOML parsing library, which this client-side tool declines to approximate. Gives exact commands for real tools instead.

How to Use TOML to JSON
  1. 1Copy the Node.js, Python, or online-tool command shown on the page
  2. 2Run it against your TOML file
Frequently Asked Questions

TOML's full grammar (dotted keys, inline tables, arrays of tables, strongly-typed dates/times) is intricate enough that a hand-written partial parser risks silently misreading valid TOML — for JSON's sibling YAML converter that risk was judged acceptable with clear limitations disclosed, but for TOML we chose not to risk a subtly wrong result and instead point to a real parser.

The page shows copy-paste-ready commands: Node.js (npm install @iarna/toml), Python (import toml), or transform.tools' online TOML ↔ JSON converter.

As a quick reference with exact working commands, rather than a fake converter that might silently produce wrong output for valid TOML syntax it doesn't fully understand.
