How To Remove Duplicates In Excel? [Complete Guide]

Excel is a popular tool, but it can be difficult to find and delete duplicates in the spreadsheet. When working with large datasets, removing duplicates is a common operation in Excel. In a spreadsheet, duplicate entries can occur when you merge data from multiple tables or when many users update the same document. This information is, thus, superfluous. The likelihood of seeing duplicate records increases as dataset size grows. If they are not properly discovered and dealt with, they might cause problems.

Using a sample sports dataset, we’ll show you how to quickly and easily delete duplicates in Excel. The 2012 Olympic medalists are included in this data set.

Seek Out And Eliminate Duplicates

While having duplicates can be helpful in some situations, it typically only complicates things. It’s preferable to find, highlight, and review duplicates before deleting them altogether.

Master The Process Of Removing Duplicates From A Dataset By Filtering For Unique Values

With the goal of obtaining a list of distinct values, you can either filter for unique values or eliminate duplicates. Each activity contributes to a larger goal. But there is a major distinction between the two. Filtering for unique values temporarily hides the duplicate values, while the remove duplicate values option deletes them permanently.

It’s also important to realize that the value displayed in a cell has no bearing on whether or not the value contained in the cell is a duplicate. If two cells both have the value “3/9/2022,” they are considered to have two different values, regardless of whether or not they are structured as a date.

Make it a habit to double-check before you delete anything in case it’s a duplicate. If you can’t get the desired results by just filtering, try conditionally formatting the unique values instead.

  • Follow these steps if you need to save the filtered data somewhere else:
  • To copy the values, select “Copy to another location” from the menu.
  • Type the cell reference into the “Copy to” box where the values should be copied.
  • To temporarily hide the pop-up window, select “Collapse Dialog” (). To continue, choose a cell on the worksheet and then go to the “Expand” menu ().
  • Mark the box labeled “Unique records only,” and then press OK.
