How to Use the INI Formatter
Paste raw INI text into the box — with [section] headers, key=value pairs, and ; or # comment lines — and it's parsed leniently and re-serialized with normalized formatting: a single consistent space around every =, one blank line between sections, trimmed whitespace, and all comments and blank lines preserved in their original position.
key=value → key = value
Example
Input debug=true (no spaces) is reformatted to debug = true, and a section immediately following a key=value pair with no blank line in between gets one inserted automatically, so every section is visually separated from the content above it.
Common Use Cases
- Cleaning up an inconsistently-formatted config file before committing it to source control.
- Standardizing spacing conventions across INI files written by different tools or people.
- Spotting a malformed line in a config file that isn't a valid section, comment, or pair.
FAQs
- What happens if my INI file has a syntax error? The formatter flags any line that isn't a valid comment, blank line, section header, or key=value pair with a warning message that includes the line number, rather than crashing or silently dropping content — the rest of the valid file is still formatted normally.
- Does this tool preserve comments and blank lines? Yes — comments (starting with
;or#) and blank lines are kept in their original position in the output, they're just not reformatted since they aren't key=value pairs or sections. - Does it support both semicolon and hash comment styles? Yes — both
;and#are recognized as comment markers, since different INI-parsing tools and languages use different conventions.
