JSON to valid INI
in your browser. No upload.

      
Root-level scalar values are placed before any sections — matching the convention of most INI parsers that expect global settings first. Nested objects inside sections are flattened with dot notation since INI has no native sub-section syntax. Values with spaces, semicolons, hashes or equals signs are automatically double-quoted.

    

    

      
Correct INI ordering
Root scalars before sections — the convention expected by configparser, php.ini and most INI parsers.

      
Auto-quoting
Values with spaces, ; # = : characters are automatically wrapped in double quotes.

      
Configurable style
Choose = or : separator, ; or # comments, and whether to include a generated-by header.

Frequently asked questions

    

      
How does JSON to INI conversion work?

      
Root-level scalar values (strings, numbers, booleans, null) are placed at the top without a section header. Each root-level object property becomes an INI [section] containing its key=value pairs. Arrays are serialized as JSON strings since INI has no native array type.

    

    

      
What happens to deeply nested JSON?

      
INI format only supports one level of nesting (sections with flat key-value pairs). Objects nested inside sections are flattened with dot notation: {database: {connection: {host: "localhost"}}} becomes [database] with connection.host = localhost.

    

    

      
Is the JSON to INI converter free?

      
Yes, completely free. No account required.
