INI output appears here
Paste JSON on the left and click ConvertEnter your JSON object in the left panel. Both flat and nested structures are supported.
Enable "Quote string values" if you need strings wrapped in double quotes in the output.
Click Convert, then copy the INI output or download it as a .ini file.
The JSON to INI Converter translates JSON objects into the INI configuration file format. Nested JSON objects become INI sections (e.g. [database]), while flat key-value pairs are written at the global level. Arrays within nested objects are flattened using dot notation.
An INI file is a simple plain-text configuration format. It consists of key-value pairs separated by =, optionally grouped into named sections using [section] headers. It is widely used in PHP (php.ini), Python, Windows applications, and many other environments.
Top-level JSON object keys that contain nested objects are converted into INI sections. For example, { "db": { "host": "localhost" } } becomes [db] followed by host = localhost. Deeper nesting is flattened using dot notation keys.
INI format does not have native array support. Arrays inside nested objects are flattened into dot-notation keys (e.g., colors.0 = red). Top-level arrays in the JSON root will be treated as sections with numeric keys.
When enabled, all string values in the output are wrapped in double quotes — e.g., name = "MyApp" instead of name = MyApp. This is required by some INI parsers that distinguish between quoted and unquoted values.
No. All conversion happens entirely in your browser using JavaScript. Your JSON data never leaves your device. The tool works fully offline once the page is loaded.
This tool converts JSON → INI only. For the reverse, use a dedicated INI parser in your language of choice (e.g., parse_ini_string() in PHP or the configparser module in Python), then serialize to JSON.
A JSON to INI converter is a developer utility that translates structured JSON data into the plain-text INI configuration file format. JSON (JavaScript Object Notation) is the dominant data interchange format on the modern web, while INI (Initialization) files are a legacy but still widely used configuration format found in PHP, Python, Windows, and countless server applications.
This tool bridges the two worlds — letting you take a JSON object and produce a clean, valid INI representation without writing a single line of parser code.

The INI format is one of the simplest configuration file standards in existence. A basic INI file looks like this:
; Global settings debug = false version = 1.0.0 [database] host = localhost port = 5432 name = mydb [cache] driver = redis ttl = 3600
The format has a few core rules:
key = value on a single line.[section_name].; or hash #.JSON and INI share the concept of key-value pairs, but differ significantly in their support for structure. Here is how our converter handles the translation:
server.timeout.connect = 30).true and false are written as true and false in the INI output.null is written as the literal string null.Several common scenarios require this kind of conversion:
configparser — Python's standard library includes configparser, which reads INI-style files. If your Python application needs to consume configuration that originates as JSON, converting it first is the cleanest approach.The INI format lacks a formal specification, which means different parsers handle edge cases differently. Here are some things to keep in mind:
key[] = value), you may need to post-process the output.Reading an INI file is straightforward in most languages. Here are quick examples:
// PHP
$config = parse_ini_file('config.ini', true); // true = process sections
# Python
import configparser
config = configparser.ConfigParser()
config.read('config.ini')
host = config['database']['host']
; Windows / .NET
; System.Configuration.ConfigurationManager reads app.config / web.config
