How This INI to JSON Converter Works
This ini to json converter lets you paste INI or .properties text and convert ini to json online instantly, one JSON object per section, no signup, no account. It's a genuine ini file parser online, reading section headers, key-value pairs, and comments the way a real INI parser would rather than a naive line split.
Bidirectional Conversion with Type Coercion
Switch direction and this doubles as a json to properties converter or json to ini converter, turning a JSON object of sections back into INI text. Unlike a plain text transform, values coming out of the properties to json converter direction are properly typed, true and false become real booleans, numeric-looking values become numbers, and null or empty values become JSON null, instead of leaving everything as raw strings the way many simple ini file parser online tools do.
Comments, Quoting, and the Global Section
This properties file parser handles both semicolon and hash comment styles, strips inline comments that trail after a value on the same line, and removes surrounding quotes from quoted string values. Keys that appear before any section header are grouped under a global section, and you can rename that group to whatever key name fits your target JSON shape.
Common Uses and Limitations
This ini parser free tool is built for reading a windows ini file to json for a legacy app config, a java properties to json conversion for an application config, or inspecting a legacy app's configuration in a more JSON-friendly shape. INI is a flat, single-level format, so this tool does not support nested or multi-level sections, and INI has no native array syntax, a repeated key simply overwrites the previous value rather than becoming a list.
