Using this tool

Convert JSON/JSON5 configuration objects to TOML, rejecting data that cannot be represented safely.

Actions: Convert

Example

The nested server object becomes a [server] table; TOML uses the serializer’s formatting.

Example action and settings

Action: Convert
Indent spaces: 2

Input / action

{"name":"Ada","server":{"port":8080}}

Result / expected behavior

name = "Ada"

[server]
port = 8080

Available options: Indent spaces

Scope and limitations

Root arrays, root scalars and null at any depth cannot be converted to TOML.

Common mistakes

Do not blindly replace null with the string "null" merely to pass conversion; that changes the data’s meaning.
