Are INI sections converted to nested objects?

Yes. A section [database] with key host=localhost becomes {"database": {"host": "localhost"}} in JSON.

How are comments handled?

Lines starting with ; or # are treated as comments and stripped from the output.

Are values automatically typed (numbers, booleans)?

Yes. Values matching "true"/"false" are converted to JSON booleans, numeric strings are converted to numbers, and other values remain strings — unless you enable the "string-only" mode to keep all values as strings.

What happens to keys without a section?

Keys appearing before any section header are placed in a top-level "default" object (or at the root level, depending on your preference setting).

INI to JSON Converter

Converts INI configuration file format to JSON. INI sections become nested objects, key-value pairs become JSON properties, and comments are stripped. Handles boolean values (true/false), numbers, quoted strings, and multi-line values. Useful for migrating legacy configurations to modern JSON-based tools.

Runs entirely in your browser — your input is never uploaded, stored, or logged.

Paste your INI config and get clean JSON output ready for any modern configuration system. After converting, use the JSON Formatter to pretty-print the result.

Examples
