The Dataset Diff tool is compatible with:.Run Dataset Diff to isolate what changed between two exports, then use Smart Merge if you need to reconcile the two files into one, or Uniqueness to confirm neither file has internal duplicate rows skewing the comparison.Dataset Diff compares two versions of a CSV row by row, matching records by key columns and reporting exactly which rows were added, removed, or unchanged between the two files. It's built for tracking how a dataset evolved over time, not for comparing raw text like a code diff tool would. Common when you export the same report weekly or monthly and need to know precisely what changed since the last export, without manually scanning thousands of rows.
