Free Online JSON Formatter & Validator

                
JSON (JavaScript Object Notation) is the backbone of the modern web, but reading raw, minified JSON payloads is a nightmare. Our JSON Formatter instantly transforms messy, unreadable data blobs into beautifully indented, structured, and colorful text.

                
More Than Just a Beautifier

                
TextCompareo's JSON tool doesn't just format your code; it acts as a strict JSON Validator. If your API response or configuration file is missing a comma, has a trailing bracket, or uses invalid quotes, our tool will catch the syntax error immediately. We provide the exact line and character position of the error so you can fix it without pulling your hair out.

Frequently Asked Questions

            

                

                        Does this tool automatically fix broken JSON?
                        
No. It parses standard JSON and reports syntax errors, but it does not guess how to repair invalid input. Review and correct the source JSON before formatting it.

                    

                

                        What can I do with valid JSON?
                        
You can format or minify valid JSON, sort keys, choose 2-space, 4-space, or tab indentation, switch between code and tree views, then copy or download the result.

                    

                

                        Does it support JSON5 or JSON with comments?
                        
No. The formatter accepts standard JSON. JSON5 syntax, comments, trailing commas, and unquoted keys will be reported as invalid JSON.

                    

                

                        How is JSON handled in this tool?
                        
Formatting and validation run in the current browser session. Do not paste secrets or regulated data unless doing so is permitted by your organization's policies.
