JSON to INI Converter

Transform nested JSON objects into standard INI configuration files. Top-level JSON keys become section headers ([section]), with nested key-value pairs flattened underneath. Perfect for Python's configparser, PHP configuration files, and legacy config systems.

Use Cases

  • Python Applications — Generate config.ini files for Python's configparser
  • PHP Projects — Create PHP-style INI configuration files
  • Legacy Systems — Bridge JSON config with INI-based tooling
  • Cross-Platform — Standard INI format works with many languages

Example

Input:

{
  "database": {
    "host": "localhost",
    "port": 5432,
    "pool": {
      "maxActive": 10
    }
  },
  "app": {
    "name": "MyApp",
    "debug": true
  }
}

Output:

[database]
host=localhost
port=5432
pool.maxActive=10
 
[app]
name=MyApp
debug=true
