Official standards and scope

Python configparser and Git each document a configuration syntax similar to INI, illustrating that INI has no single interoperable standard. This page implements its own small dialect. It removes everything from the first semicolon or hash on every line, including such characters inside a quoted value, accepts section headers and key=value lines only, permits keys before any section, and overwrites duplicate keys. Values surrounded by matching single or double quotes lose those quotes; true/false and simple decimal numbers become typed values; bracketed comma-separated text becomes a shallow array. There is no escaping, multiline value, interpolation, default section, repeated key, nested section, colon delimiter, or dialect selection. Formatting discards comments, emits arrays as comma-space text, and may not round-trip strings or types. The JSON view reflects this parser's object, not compatibility with Windows, Python, Git, or another INI consumer.

FAQ

Are comments preserved?

Comments are ignored in JSON output and removed from formatted output for clean config review.

Is INI Formatter JSON free to use?

Yes. You can use it directly in the browser without creating an account.

Does INI Formatter JSON support batch processing?

Text tools usually process one pasted input at a time, so split large jobs into smaller inputs.

Are files or content uploaded?

INI Formatter JSON runs in your browser, so your input or files are not uploaded to DataHub servers.

Can I use INI Formatter JSON on mobile?

Yes, but desktop browsers are better for large files, batch conversion, or long text input.

Why can conversion or validation fail?

Common causes include invalid syntax, missing required fields, or invisible characters copied with the input.

Can I use the result commercially?

The tool only processes your own input. Commercial use depends on the rights of the original file or data.
