How It Works

  
Paste your JSON data and format it with proper 2-space indentation and syntax highlighting. The validator catches errors instantly and shows the exact location of problems. Switch to minify mode to compress JSON for APIs and storage — it shows how many characters were saved. Everything runs locally in your browser, so your data stays private.

  
Frequently Asked Questions

  

    

      Does it validate JSON?+
      
Yes. If your JSON has syntax errors, it shows the exact error message with position.

    


    

      Can I minify JSON?+
      
Yes, click Minify to remove all whitespace. Shows how many characters were saved.

    


    

      What indentation?+
      
Standard 2-space indentation for maximum readability.

    


    

      Is there a size limit?+
      
Works with JSON up to several megabytes. Very large files may cause temporary slowdown.

    


    

      Does it fix broken JSON?+
      
It validates and reports errors but doesn't auto-fix them. You need to correct the syntax manually.
