CompareSheets

CompareSheets is an advanced Microsoft Excel add-in that intelligently compares two worksheets using unique identifiers — going far beyond basic cell-by-cell comparison.

🔒 100% privacy – your Excel files never leave your computer.

All processing happens locally. No cloud storage.

It automatically detects and highlights in a single output:

• New rows and columns
• Updated values: Updated_OLD (values from the old file) and Updated_NEW (values from the new file)
• Deleted rows and columns
• Matching values

The CompareSheets add-in includes a built-in algorithm that automatically identifies unique key (identifier) columns.

You can optionally skip specific columns from being highlighted as changes (e.g., a timestamp column or other automatically generated values) without affecting the data copied from each file.

This makes it simple to track changes, reconcile records, and ensure data accuracy — all without leaving Excel.

Ideal for: Clinical Data Managers, Consultants, Supply Chain Teams, HR & Compliance Professionals, and Financial Analysts.
