F.A.Q
Everything you need to know about our JSON engine.
Is my JSON data stored on your servers?
No. All processing, formatting, sorting and validation happens locally in your browser. Your data is never stored or transmitted.
What does 'Sort Keys' do?
It recursively reorders all object keys alphabetically while preserving array order — great for diffing two JSON files or producing canonical output.
Can I convert raw text to a JSON string?
Yes. 'Escape' turns any raw text into a valid JSON string (escaping quotes, newlines, etc.), and 'Unescape' does the reverse.
Does it show where my JSON is broken?
Yes. The validator reports the error message along with the line and column of the first problem it finds.
What is the Tree view?
The Tree view renders your JSON as a collapsible, colour-coded hierarchy so you can explore deeply-nested structures without scrolling through raw text.
