Paste an INI file — php.ini, my.cnf, a .gitconfig, a desktop app's settings — and get JSON. Sections become objects, keys become properties, comments are left behind.
Runs entirely in your browser — nothing you enter here is sent to a server.
INI files are the oldest configuration format still in everyday use: lines of key = value, grouped under [section] headings, with comments starting with a semicolon or a hash. PHP, MySQL, Git, systemd units, Python's configparser and countless desktop applications read some dialect of it. There is no formal standard, which is exactly why converting to JSON helps — JSON has one unambiguous structure that every language can parse.
[server] opens an object named server. Keys before the first section sit at the top level.
[alerts.email] becomes {"alerts": {"email": {…}}}, the usual way INI files express a hierarchy.
PHP-style key[] = value, or the same key given twice, collects the values into an array.
Quoted values are kept as strings. Unquoted ones are typed when detection is on: 8443 is a number, true a boolean. Trailing comments are removed.
The usual reasons are practical. You want to read settings from a legacy application in a script that speaks JSON. You are moving an old service to a platform configured through environment variables or a JSON document. Or you need to compare two configurations — once both are JSON, sorted and formatted the same way, a diff shows exactly which values differ. Both = and : are accepted as the separator, so most dialects convert without editing.
A plain-text configuration file made of key = value lines, optionally grouped under [section] headings. The name comes from the .ini extension Windows used for "initialisation" files.
No. Lines starting with ; or # are skipped, and a comment after an unquoted value is removed. JSON has no comments, so they cannot be carried over.
With type detection on, unquoted numbers, true/false and null are converted to JSON types. Turn it off to keep every value as a string, exactly as written.
Section names containing dots, such as [database.replica], are converted to nested objects.
