Is this JSON formatter private?
Yes. Standard formatting runs locally in your browser, with no dedicated backend for processing the JSON you paste.
Does my JSON leave the browser?
No, not through the tool execution. Text pasted into the JSON field is formatted in the browser.
Can I minify JSON too?
Yes. Use the related JSON Minifier tool when you need compact single-line JSON for payloads or tests.
What happens if my JSON is invalid?
The formatter shows a validation error. Check for missing commas, quotes, closing brackets, or closing braces.
Can I format large JSON files?
Large payload performance depends on your browser and device memory. Validate the output before using it in production.
