About
Use this utility to check JSON validity and format it for readability.
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.
When to use it
Use it when debugging API responses, preparing fixtures for tests, or cleaning JSON copied from logs and external services.
