FAQ
Is this JSON formatter private?
Yes. Formatting and validation run in your browser so pasted payloads stay local during formatter actions.
Why do I see parse line and column in errors?
The formatter extracts parse position details from browser JSON parsing errors to help you find the invalid character faster.
What does Sort Keys do?
Sort Keys recursively sorts object keys alphabetically so generated JSON stays stable across environments.
Can I use this as a JSON validator?
Yes. Use Validate to check syntax without rewriting output, then switch to Text View or Tree View for inspection.
