How to Compare Two Excel Files for Duplicates?

We will be covering topics such as using the VLOOKUP function, using Conditional Formatting, and using text comparison functions to make the task of identifying duplicates much easier. So, without further ado, let’s get started and learn how to compare two Excel files for duplicates.

Using the ‘Conditional Formatting’ Feature to Compare Excel Sheets for Duplicates

Microsoft Excel offers a built-in feature called ‘Conditional Formatting’ that allows you to quickly and easily compare two Excel sheets for duplicates. This feature can be used to spot identical records across sheets, highlight cells that display the same values, and find and highlight unique records. In this article, we’ll explain how to use the Conditional Formatting feature to compare two Excel sheets for duplicates.

The Conditional Formatting feature works by applying a set of rules to a range of cells in an Excel sheet. When the conditions of the rules are met, the cells are highlighted according to the specified formatting. To compare two Excel sheets, you will need to create a ‘rule’ that specifies the conditions that must be met in order to highlight the cells as duplicates.

To begin, select the range of cells in the first Excel sheet that you want to compare. Then, select the ‘Conditional Formatting’ option from the ‘Home’ tab on the Ribbon. From the drop-down menu, select the ‘Highlight Cells Rules’ option. Next, select the ‘Duplicate Values’ option from the list of rules. This will open a dialog box where you can specify the formatting you would like to apply to the cells that meet the criteria of the ‘Duplicate Values’ rule.

Specifying the Duplicate Values Rule

Once you have opened the ‘Duplicate Values’ dialog box, you will need to select the cells in the second Excel sheet that you want to compare. To do this, click the ‘Choose another range’ option in the dialog box and select the range of cells in the second sheet. Once you have selected the range, you can specify the formatting you would like to apply to the cells that are identified as duplicates.

In the ‘Duplicate Values’ dialog box, you can select the color of the cell highlighting, the font style, and the font size. You can also specify if the highlighting should be applied to the entire row or just the cell that contains the duplicate values. When you have finished specifying the formatting, click the ‘OK’ button to apply the formatting to the cells that meet the criteria of the ‘Duplicate Values’ rule.

Testing the Duplicate Values Rule

Once you have applied the ‘Duplicate Values’ rule, you can test it to make sure that it is working correctly. To do this, you will need to enter some data into the cells in both Excel sheets that meet the criteria of the rule. For example, if you have specified that the rule should highlight cells that contain the same value, you should enter the same value into some of the cells in both sheets. Once you have entered the data, the cells should be highlighted according to the formatting you specified in the ‘Duplicate Values’ dialog box.

Using the Duplicate Values Rule to Compare Multiple Sheets

You can also use the ‘Duplicate Values’ rule to compare multiple Excel sheets. To do this, you will need to create a separate ‘Duplicate Values’ rule for each sheet you want to compare. You can then specify different formatting for each rule to make it easier to identify the duplicates in each sheet. Once you have created the rules, you can test them by entering some data into the cells in each sheet and verifying that the cells are highlighted correctly.

Removing the Duplicate Values Rule

If you no longer need the ‘Duplicate Values’ rule, you can remove it by selecting the range of cells that you applied the rule to and then selecting the ‘Conditional Formatting’ option from the ‘Home’ tab on the Ribbon. Next, select the ‘Clear Rules’ option from the drop-down menu. This will remove the ‘Duplicate Values’ rule and the formatting will be removed from the cells.
