Frequently asked questions
Does key order matter?
No. JSON objects are unordered, so this compares by key. Array order does matter.
Is the JSON Diff free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Do I need an account?
No. The tool is free, needs no sign-up and runs in your browser.
