Frequently Asked Questions

What is an INI file?
INI (Initialization) files are simple text-based configuration files with sections in [brackets] and key=value pairs. They're used by PHP, MySQL, Windows, and many applications.
Does this handle INI sections?
Yes. Sections like [database] are converted to nested JSON objects. Keys outside any section become top-level properties.
Are comments preserved?
Comments (lines starting with ; or #) are ignored during parsing, as JSON doesn't support comments.
Does it handle data types?
Yes. The parser automatically detects numbers, booleans (true/false), and strings. Quoted values are treated as strings.
Is my data safe?
Absolutely. All parsing happens in your browser. No data is sent to any server.
