Frequently Asked Questions
How does JSON compare work?
Our diff engine runs a line-by-line comparison using a Longest Common Subsequence (LCS) layout. It maps changes in matching arrays, identifies nested keys, and isolates added, deleted, or modified lines.
What does "Ignore Formatting" do?
When active, both input blocks are parsed into JavaScript objects and pretty-printed with identical indentation (2 spaces) before comparing. This filters out false differences caused by tab indentation styles or layout linebreaks.
