Frequently asked questions
Does key order matter when comparing JSON?
In JSON objects it does not, because they are unordered. Array order does matter, so reordered items show up as differences.
How are arrays compared?
Arrays are compared position by position, so inserting an item at the start can show many changes. Sort the arrays first if order is not important.
Why does the diff show a change when values look the same?
The types can differ, for example the number 5 and the text 5. Check quotes and whitespace in the values.

Yes. JSON diff on Toolipedia is free to use, with no sign-up and no watermark.
