Frequently Asked Questions
What can I compare with the JSON diff tool?
You can compare API responses, configuration files, saved snapshots, test fixtures, or any two JSON objects.
Does key order affect the diff?
Object key order usually should not change the meaning of JSON. Formatting or sorting options can make meaningful value changes easier to see.
Can I use it for API regression testing?
Yes. Paste an old and new response to quickly spot added fields, removed fields, changed values, or structural differences.
