About the JSON diff tool

Both documents render as full trees, side by side, with the exact node that differs highlighted in place — green for something only present on the right, red for something only present on the left, amber for a value that changed. A dashed amber marker appears on any collapsed container that has a change somewhere inside it, so collapsing a branch never hides that something underneath changed.

FAQ

Does array order matter?

Yes — arrays are compared index by index, so reordering items will show as changes.

Why is only one side highlighted for an added/removed key?

An added key only exists on the right, and a removed key only exists on the left — there's no node on the other side to highlight.
