Using this tool

Convert TOML keys, tables and arrays into JSON data structures.

The [server] table becomes a nested JSON object with two-space indentation.

Example action and settings

Action: Convert
Indent spaces: 2

Input / action

name = "Ada"
[server]
port = 8080

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

Scope and limitations

TOML date/time values become strings through JSON serialization; comments and original TOML formatting are not retained.

Common mistakes

TOML integers outside JavaScript safe precision cause an error; they are not automatically converted into strings.
