API debugging workflow
A readable JSON formatter for API payloads, config samples, and quick validation.
The JSON Formatter is one of those tiny tools that earns its keep during real debugging. When an API response, configuration blob, or test payload is jammed into one line, formatting it makes the structure visible again. Minifying does the opposite when you need a compact payload for a test case or documentation example.
This page is intentionally narrow: paste JSON, format it, validate it, copy it, or download it. That directness matters because JSON problems are usually small but annoying: a missing comma, the wrong nesting level, a property in the wrong object, or an array that should have been a single value.
Use sanitized data when working with client records, credentials, or private configuration. The utility is browser-based, but good habits around sensitive payloads matter everywhere.
