How to format JSON

                        
JSON (JavaScript Object Notation) is the standard format for data exchange between applications. JSON often arrives minified (a single line, no spaces) to reduce size. The formatter makes it readable by adding indentation and separate lines. Paste your JSON, click "Format" and get a clean output with 2-space indentation.

Common JSON errors

                        
The most frequent bugs: trailing commas, unquoted keys, single quotes instead of double, comments (not allowed in standard JSON). The validator tells you the line and column of the error so you can fix it quickly.
