What is JSON Formatter?
A JSON formatter reorganizes minified or badly indented text into a readable structure with consistent indentation and highlighting, and instantly warns you if the JSON is invalid, pointing to where the error is. It can also minify it to reduce its size before sending it over the network.
It's one of the most used utilities for any developer working with APIs: pasting an endpoint's response to read it comfortably, validating a config file, or cleaning up JSON copied from logs. Everything happens in your browser, so you can format sensitive data without it leaving your machine.
