About the JSON to INI Converter

INI files refuse to die: php.ini, my.cnf, Git config, desktop entries, countless Windows and game settings all use the same simple sections-and-keys format. When the settings you have are JSON — from an API, an export or a modern config — you need them rewritten in a shape those readers understand.

Paste JSON and get INI. Top-level values are written first, objects become [sections], and objects inside objects become dotted sections such as [database.options] — the nesting convention PHP’s parse_ini_file, Python’s configparser and most other readers follow. Arrays can be written as repeated key[] lines in PHP style, as numbered key[0] entries, or joined onto a single comma-separated line. Values containing ; # = or a quote are quoted, because an unquoted ; starts a comment and would silently truncate the value.

Key features of the JSON to INI Converter

Dotted sections

Nested objects become [database.options], the convention most INI readers use.

Three list styles

key[] for PHP, key[0] for indexes, or one comma-separated line.

Comment-safe values

Values containing ; or # are quoted so they are not truncated when read back.

Boolean style

Write true/false or on/off to match what the reader expects.

Optional header

Add a generated-on comment at the top of the file.

    key[] for PHP, key[0] for numbered entries, or one comma-separated line.

  3. 3

    Pick the details

  4. 4

    Copy or download the .ini

    Drop it into your application or service configuration.

Frequently asked questions

One level becomes a [section]. Deeper levels become dotted sections such as [database.options], which PHP, configparser and most INI readers understand as nesting.
