JSON Formatter
Paste your JSON below — we'll format, minify, and syntax-check it for you!
- Paste your JSON string into the input box.
- Click "Format (2 spaces)" or "Format (4 spaces)" to beautify JSON, or click "Minify" to remove extra whitespace.
- If JSON is invalid, an error message appears below the input in real time.
- Click "Copy" to quickly copy the result.
When would I use this?
- When reading API responses, config files, or exported data that is hard to scan in raw form.
- When you need to pretty-print JSON for debugging or minify it before embedding it somewhere.
- When you want quick syntax feedback before sending JSON to another tool or service.
What is the difference between formatting and minifying?
Formatting adds indentation and line breaks to make JSON readable. Minifying removes extra whitespace to make the payload smaller while keeping the same data.
Why is my JSON showing an error?
Common causes are missing commas, unmatched brackets, extra trailing commas, or using single quotes instead of double quotes for strings and keys.
Does this tool change my data values?
No. A valid format or minify action changes layout only, not the actual JSON structure or values.
When should I choose 2 spaces versus 4 spaces?
Use 2 spaces for compact readability and 4 spaces when you want deeper nesting to stand out more clearly. The better option depends on your team style and document size.
What Is JSON Minification? When Do You Need It?
JSON minification removes unnecessary whitespace, line breaks, and indentation from JSON text to reduce file size and speed up network transfers. This article explains how it works, when to use it, and when to skip it.
