About JSON to Properties
Convert JSON configuration to Java .properties format, .env files, or INI-style configs. Nested objects are flattened using dot notation (or custom delimiters).
Output Formats:

- .env: Environment variables with UPPER_CASE keys
- INI: Grouped by top-level keys as sections
Example:
// JSON Input:
{"db": {"host": "localhost", "port": 5432}}
// .properties Output:
db.host=localhost
db.port=5432
