Excel is a powerful tool that allows users to organize and manipulate large amounts of data. However, with great power comes great responsibility, as the saying goes. One of the challenges users face when working with Excel is dealing with duplicates or finding identical data in different sheets or columns. In this article, we will explore some tips and tricks for identifying duplicate data in Excel, as well as how to find identical data across multiple sheets.
How to Identify Duplicate Data in Excel
Excel provides several built-in features for identifying duplicate data in a spreadsheet. Here are some tips on how to use these features:
1. Conditional Formatting:
Conditional formatting allows users to apply formatting options such as font color, cell highlighting, and borders to cells that meet certain criteria. One of the criteria is to apply formatting to duplicate values. Here are the steps to apply conditional formatting to duplicates:
- Select the range of cells that you want to check for duplicates
- Go to the Home tab and click on Conditional Formatting
- Select Highlight Cells Rules and then choose Duplicate Values
- Choose the formatting style you want to apply to the duplicates and click Ok
The cells containing duplicate values will now be highlighted according to the formatting options you chose.
2. Remove Duplicates:
The Remove Duplicates feature in Excel allows users to quickly eliminate duplicate values in a column or range of cells. Here are the steps to remove duplicates:
- Select the range of cells that you want to remove duplicates from
- Go to the Data tab and click on Remove Duplicates
- Choose the columns that you want to check for duplicate values
- Click Ok
All duplicate values will now be removed from the selected range of cells.
How to Find Identical Data Across Multiple Sheets
Excel also provides several built-in features for finding identical data across multiple sheets. Here are some tips for using these features:
1. Using the VLOOKUP Function:
The VLOOKUP function is a powerful tool for finding matching data across different sheets in Excel. Here are the steps to use the VLOOKUP function:
- Select the cell where you want to display the matching data
- Type =VLOOKUP(

- Type a comma
- Type False
- Type ) and press Enter
The cell you selected should now display the matching data from the second sheet.
2. Using the Consolidate Function:
The Consolidate function in Excel allows users to combine data from multiple sheets into a single sheet. Here are the steps to use the Consolidate function:
- Select the range of cells in the new sheet where you want to display the consolidated data
- Go to the Data tab and click on Consolidate
- Select Sum
- Choose the range of cells in each sheet that contains the data you want to consolidate

All data from the different sheets will now be combined into a single sheet.
FAQs:
Q: Can I use conditional formatting to highlight unique values?
A: Yes, you can use conditional formatting to highlight unique values as well. Instead of choosing Duplicate Values in the Highlight Cells Rules option, choose Unique Values.

A: Yes, when selecting the columns to check for duplicates in the Remove Duplicates feature, simply select multiple columns instead of just one. Excel will then consider duplicates only if the values in all selected columns match.
