A simple JSON workflow for developers

        
Clean up API responses, configuration files and JSON payloads without installing a separate editor extension.


        

            
Step 01
Paste your JSON
Drop an API response, configuration object or copied JSON into the input editor.

            
Step 02
Validate & format
Choose your indentation level and format the input. Invalid syntax is surfaced immediately.

            
Step 03
Copy or download
Take the resulting JSON into your editor, terminal, API client or application.

        


        

            
About JSON formatting

            
Formatting changes whitespace and indentation without changing the underlying JSON data. Minification removes insignificant whitespace so the same JSON uses less space.
