How to Combine Duplicates in Excel

If you’ve ever worked with Microsoft Excel, you know that dealing with duplicate entries can be frustrating and time-consuming. It’s not uncommon to find yourself with a spreadsheet that has multiple instances of the same data, which can make it difficult to analyze and draw accurate conclusions from your data. In this blog post, we’ll show you how to combine duplicates in Excel so that you can streamline your data and make it more manageable.

Identify the Duplicates

The first step to combine duplicates in Excel is to identify the duplicate entries in your spreadsheet. This can be done by using the “Conditional Formatting” feature in Excel. Select the data range of your sheet and click on the “Conditional Formatting” button in the “Home” tab. Click on “Highlight Cells Rules” and then “Duplicate Values”. Excel will highlight all the cells that have the duplicate entries that need to be combined.

Combine Duplicates within a Single Column

If you have duplicates in a single column, the “Remove Duplicates” function in Excel can quickly help you to combine them. Select the column with duplicates and click on “Data” tab. Click on “Remove Duplicates” and select the column you want to remove duplicates from. Excel will prompt you to confirm which columns to remove duplicates. Click “OK” to remove duplicates.

Combine Duplicates in Multiple Columns

If you have duplicates in multiple columns, a formula can be used in Excel to combine the duplicates, into one cell. Here’s how: In an empty cell, type in the formula =A2&” “&B2&” “&C2 (where A2, B2, and C2 are the cells that you need to combine) and press “Enter”. This will combine the cell values into a single cell. Copy the formula and paste it in the remaining cells and press “Enter” to populate the new cell with the combined value. Use the “Remove Duplicates” function to remove duplicate values in the consolidated cells.

Combine Duplicates across Multiple Sheets

If you’re working with multiple sheets, combining duplicates across those sheets is possible. You can use the “Consolidate” function in Excel. Select all the sheets you want to consolidate data from and click on “Data” tab. Then click on “Consolidate” and select the reference criteria for your data. Once the data has been consolidated, you can use the same steps outlined in previous sections to remove duplicates.

Conclusion

Combining duplicates in Excel doesn’t have to be a daunting task. By following the steps outlined in this blog post, you can streamline your data and make it more manageable. Whether you have duplicates in a single column or across multiple sheets, Excel has tools and functions that will make the process easier.

Using Excel Add-Ins to Combine Duplicates

In addition to the built-in functions in Excel, there are various add-ins available that can help you to combine duplicates. For example, the “Remove Duplicates Manager” add-in can quickly and easily help you to identify and remove duplicates in your spreadsheet. Another useful add-in is “Duplication Manager,” which can be used to find and combine duplicates in your data.
