JSON Formatter: When and How to Use It
Format, validate, and minify JSON for APIs and development
By Ben Praveen J · July 10, 2024 · Updated February 2026
JSON is the standard format for APIs and config files. Raw JSON is often minified—hard to read. A JSON formatter adds indentation, validates syntax, and can minify for production. Use it when debugging API responses, inspecting configs, or preparing JSON for storage.
Step-by-Step
Paste your JSON into the input area.
Click Format for indentation or Minify to remove whitespace.
Copy the output. Invalid JSON will show errors.
