Standard text comparison tools like 'diff' or 'git diff' treat JSON as flat text lines. If an API returns keys in a different order or with alternative spacing, text diff tools report hundreds of changes even when the data semantics are 100% identical. Semantic JSON diffing solves this problem by parsing data trees before comparing.
Lexical vs Semantic Tree Comparison
Semantic comparison normalizes object keys and array indices into canonical abstract syntax trees. Only actual data modifications, additions, or deletions are highlighted.
