Worksheets are compared one versus one, grouped into pairs. Excel Compare needs to know which pairs of sheets you are going to compare. Comparison Wizard
gives you a control on this process. Here you need to define data to be compared.
Excel Compare groups worksheets with same names into pairs and give you a preliminary list of sheets to be compared.
Wizard is divided into 3 parts – Worksheets, VBA Modules and VBA Forms. Every tab display list of the grouped items.
Checked items will be included into comparison, unchecked ones – excluded.
You can change pairs and re-group the worksheets and VBA Modules and Forms in the Wizard Tabs.
In our example there is only 1 worksheet named Laptops and 2 Visual Basic Modules – Sheet1 and ThisWorkbook. We left this pair checked.
Our worksheet has only pricing records, and doesn’t have Visual Basic Code, so we can ignore VBA items.
We select VBA Modules tab and use Exclude All button. This tells Excel Compare to excludes all VBA Module items. They immediately appear unchecked in the list.
On the Worksheets tab Laptops item is checked and has Key icon. This means that Excel Compare will use Compare by Primary Key algorithm for this sheet.
Double click on this item or Edit button below this list opens window where you can change the algorithm.
In our case initial selection is right and should not be changed.
