how to compare two excel sheets

To compare two Excel sheets, you have several effective methods depending on your needs and Excel version:

1. Use Microsoft Spreadsheet Compare Tool (Professional Plus or Microsoft

365 Enterprise)

• Open Spreadsheet Compare from the Start menu or Excel's Data tab under Data Tools.
• Click Compare Files , select the two Excel workbooks or sheets you want to compare.
• Choose comparison options such as formulas, macros, or cell formatting.
• Run the comparison to see a side-by-side view highlighting differences by color, with details below the grids

2. View Side by Side in Excel

• Open both Excel files.
• Go to the View tab and click View Side by Side.
• Scroll through both sheets simultaneously to visually spot differences

3. Use Formulas for Cell-by-Cell Comparison

• In a new column, use a formula like:

  =IF(Sheet1!A1=Sheet2!A1, "Match", "Difference")
  

• Drag the formula across the range to identify matching or differing cells.

• For case-sensitive comparison, use EXACT function.

• For more complex matching, use VLOOKUP or XLOOKUP to compare datasets based on key columns

4. Conditional Formatting to Highlight Differences

• Apply conditional formatting rules to one sheet to highlight cells that differ from the corresponding cells in the other sheet.
• This method visually marks differences without needing a separate tool

5. Use Third-Party Add-ins or Online Tools

• Some add-ins (like Ablebits) offer advanced comparison features, including filtering differences by content type or format and comparing selected ranges
