Frequently asked questions
How many JSON files can I compare?
Two to four at once, with a summary of what differs and where.
Does key order matter?
No. Objects are compared by key, so a different key order does not create false differences.
Is my JSON uploaded?
No. The comparison runs entirely in your browser.
