INI Parser — Convert Config Files to JSON, YAML or TOML

Parse INI, .conf, .cfg and .properties files into structured JSON, YAML or TOML.

INI files are section headings in square brackets followed by key/value pairs. This parses them — along with .conf, .cfg and .properties files — into JSON, YAML, TOML or .env format, inferring types so that `port = 8080` becomes a number and `tls = true` becomes a boolean, while a quoted value stays a string.

Frequently asked questions

Why is my quoted number staying a string?

Deliberately. Quoting is the only way an INI file can say "treat this as text", and it matters for values like version numbers and zero-prefixed codes — `version = "1.20"` must not become 1.2, and `zip = "01234"` must not lose its leading zero.

Is there a single INI standard?

No, which is why parsers disagree. There is no specification — comments may start with ; or #, separators may be = or :, some dialects support nested sections through dots, and duplicate keys mean different things in different tools. This handles the common intersection and reports lines it cannot make sense of rather than guessing.
