Is my JSON data uploaded to a server?
No. All JSON formatting, validation, and minification runs directly in your browser. Your data stays on your device and is never transmitted anywhere.
What does "Sort keys" do?
When enabled, object keys in your JSON output are sorted alphabetically. This makes it easier to compare two JSON documents or to find a specific key in a large object.
What is the difference between formatting and minifying?
Formatting adds indentation and line breaks to make JSON human-readable. Minifying removes all unnecessary whitespace to make the JSON as compact as possible — ideal for API responses and data storage.
How do I fix a JSON parse error?
The validator shows the exact error message and position. Common issues include missing commas, trailing commas (not allowed in JSON), unquoted keys, or using single quotes instead of double quotes around strings.
