## What is Vlookup used for in Excel?

Vlookup is an in-built function that is used to search and find specified data within Microsoft Excel. It searches for a particular value in a certain column of a table or range of cells and returns the corresponding value from the same row in another column of the table. This is an extremely useful tool for quickly finding data in large spreadsheets. Vlookup is used to verify data accuracy and to find duplicate values or entries.

### How to Use Vlookup to Find Duplicate Values in Excel

The first step in using Vlookup to find duplicate values in Excel is to create a data table with all the values you want to search for. This can be done by selecting the range of cells you want to search and then going to the Data tab, choosing the Data Table option, and entering the column of values you want to search.

Once you have your data table set up, you can then use the Vlookup function to search for duplicate values. To do this, select a cell in the data table and enter the Vlookup formula. The formula should include the cell you want to search, the table range, the column number of the value you want to search, and the approximate match option.
