verified May 27, 2026

Prettier plugin that expands all JSON arrays and objects into multi-line format, ensuring consistent formatting for JSON and JSONC files. Current stable version 1.0.4, released with no dependencies. Engine requires Node >=20. Unlike default Prettier behavior which may collapse short objects, this plugin always forces multi-line output. Works with special files like package.json and composer.json, and can be combined with other JSON plugins (must be listed last).
