SheetDiff is built for Google Sheets™ comparison and reconciliation workflows within the currently open spreadsheet.
Compare two tabs using key columns, review added, removed, and changed rows, and generate clear report sheets without manual copy/paste.
When changes need to be carried back into your source data, SheetDiff helps you review duplicates, prepare merge decisions, and apply approved updates with confirmation.

Use SheetDiff for finance reconciliations, operations reviews, inventory updates, customer list cleanup, and any workflow where two tabs in the same spreadsheet need to be compared and safely brought back
  into sync.
Pro features in the current version include larger reconciliations, side-by-side review, exports, highlighting, saved presets, duplicate resolution, and merge review workflows.
