What INI features are supported?

Sections (bracketed headers), key=value and key:value pairs, inline comments with ; or #, quoted string values, and global keys outside any section.

Are comments included in the JSON output?

No. INI comments (lines starting with ; or #, and inline comments after values) are stripped because JSON has no comment syntax.

How are numbers and booleans handled?

Values that look like integers or floats are converted to JSON numbers. Values of true/false/yes/no/on/off (case-insensitive) are converted to JSON booleans.

What happens to duplicate keys within a section?

The last value wins, matching standard INI parser behavior used by most runtimes.

Is my config data sent anywhere?

No. All parsing and conversion happens locally in your browser using JavaScript. Nothing is transmitted to any server.
