SheetDiff is a sheet comparison and spreadsheet diff tool for Google Sheets™.
Compare two tabs in the same spreadsheet using key columns. Find differences between sheets, review added rows, missing rows, removed rows, changed rows, duplicate keys, and matching rows, and
generate clear diff report sheets without manual copy/paste.

The add-on works inside the spreadsheet you already have open. Choose two tabs and compare sheets without leaving Google Sheets™.

 Use SheetDiff for everyday data workflows:
- Finance and operations: spreadsheet consolidation, operations reports, monthly finance checks, account reviews, and reconciliation workflows.
- Data QA and cleanup: CRM cleanup, spreadsheet version comparison, duplicate key review, customer list cleanup, and vendor list checks.
- Inventory and logistics: inventory updates, order exports, vendor updates, product lists, and operations reports.

Safe merging and highlighting:
When differences need to be merged back into your source data, SheetDiff helps you review duplicates, prepare merge decisions, and apply approved updates with confirmation. You can also highlight
differences directly on the source sheets to see exactly what changed.
