  • Drop smaller file into Right Panel (FILE2)
  • After this you see both worksheets opened one versus one
  • Press Compare button on the Home tab.
  • It shows you the Comparison Wizard. If your excel workbooks contain several sheets - make sure that sheets are selected by pairs properly. In this wizard you can modify the selection. But usually you can just complete the Wizard immediately without any additional actions.

  • Use the Bulk Merge command below the report. This command opens Merge Wizard where you need to select desired operation you would like to perform with your datasets.
  • Choose Create Difference of Two Tables on the Left Sheet. Thats All! After you run this command in a few seconds you get records from the bigger sheet on the left.
Now you can work with the output dataset. As you've stated in the description - you need a third worksheet with output records. So, please use the Save As command to save a copy of the output worksheet, without modifying your bigger file.
