INI to JSON
Convert INI configuration files to JSON and back: [section] blocks, both = and : separators, ; and # comments, whitespace trimming, duplicate-key strategies (last wins / error / array) and globals collected into a default section.

What this tool does
- Turn legacy INI files (php.ini, desktop apps, config.ini in build scripts) into JSON you can require straight from Node or a frontend bundle.
- Write a JSON config back out as INI for older systems and ops scripts that only read INI.
- Flatten an INI file into JSON while debugging, so you can see every section, key and duplicate at a glance.
Example
Input
name = app [server] host = localhost port = 8080
Output
{
"default": {
"name": "app"
},
"server": {
"host": "localhost",
"port": "8080"
}
}Values stay strings; keys written before any section go into the default section.
Frequently asked questions
What happens to duplicate keys?
By default the last value wins, but you can switch to "report error" or "collect into array". Either way the duplicated key names are listed under the result so you can clean the file up.
Are colons or equals signs inside a value treated as separators?
No. Only the first = or : on the line is the separator, everything after it is the value, so URLs like http://a.com?x=1 survive unchanged.
How are nested objects handled when converting JSON back to INI?
One level of nesting becomes a [section] and root-level scalars go into the default section. Deeper nesting, or objects inside arrays, cannot be expressed in INI and raise an error.
Are comments supported?
Yes. Lines starting with ; or # are ignored, while # characters inside a value (colors, URL fragments) are kept.
