Frequently asked questions
Does whitespace affect the result?
No. Both documents are parsed before comparison, so spaces, line breaks, and object key order are ignored.
How are arrays compared?
Array order and position are significant. An item at $.items[1] is compared with the item at the same position in the other document.
Can I share a comparison with someone?
You can share the tool link, but document content is never placed in the URL. Copy or download the report locally when you need to send the result.
