Reconcile two datasets you supply and get one answer plus every disagreement
Reconcile two datasets you supply and get one answer plus every disagreement. Reports keys present on only one side, keys duplicated on either side, whether the join is really 1:1 or silently N:M, and field-level differences with the row number on each side. Numbers compare exactly on their decimal text, never through floating point, so 42.50 and 42.5 agree while 9007199254740992 and 9007199254740993 do not. A repeated key is compared as an unordered multiset. Nothing is fetched.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
