TOML → JSON

Parse TOML configuration into JSON.

Private by design. Your input never leaves this browser. Conversions run locally on your device.

What this tool handles

TOML dates and date-times become ISO 8601 strings.
Tables, inline tables and arrays of tables all become plain JSON objects and arrays.
Invalid TOML reports the line and column rather than a raw parser message.

title = "DevConvert"

[owner]
name = "Ada"
active = true

{
  "title": "DevConvert",
  "owner": {
    "name": "Ada",
    "active": true
  }
}
