Frequently Asked Questions
How does JSON Compare work?
The tool first validates both JSON inputs. If valid, it parses and formats them, then performs a line-by-line comparison while also tracking semantic changes at the property level.
What does "Sort keys" do?
When enabled, object keys are sorted alphabetically before comparison. This helps compare JSON objects where the same data may be in different order.
What's the difference between line changes and semantic changes?
Line changes show the actual text differences. Semantic changes count how many JSON properties were added, removed, or modified, giving you a higher-level view of the changes.
