What is a JSON formatter?

A JSON formatter takes JSON text and rewrites it in a consistent structure. It helps you quickly read nested objects and arrays while preserving the same data.

Validation and minification

The tool validates your input before formatting. You can also minify JSON to remove whitespace and produce a compact payload for APIs and network transfer.

Kiedy to stosować

Use it when debugging API responses, preparing fixtures for tests, or cleaning JSON copied from logs and external services.
