Conditional Formatting – How to Highlight Duplicates
To simplify identifying duplicates in a single column, conditional formatting is an easy tool that can be used. By highlighting identical values, you can get rid of duplicate data efficiently.
Here’s a 4-step guide on using conditional formatting:
- Select the entire range of data from which you want to highlight the duplicates.
- Click on the ‘Conditional Formatting’ option in the ribbon and select ‘Highlight Cell Rules’ followed by ‘Duplicate Values.’
- In the dialogue box that appears, choose the colour with which you wish to highlight your duplicates.
- Press ‘OK’, and all duplicate cells will be highlighted in the selected colour within seconds.
A significant advantage of conditional formatting is its ability to quickly alter or remove formats created due to changes made in the underlying data.
Pro Tip: Use this tool for cross-validation of large amounts of data with many fields.
Finding duplicates in multiple columns is like playing hide and seek with data, except the data never moves and you’re the one hiding from sanity.

Using Excel’s built-in tools
To uncover duplicates across multiple columns in Excel, you can utilize Excel’s built-in functions. Here is a 6-step guide to help you identify duplicates using these tools:
- Select the data range that contains the columns you want to compare for duplicates.
- Go to the ‘Data’ tab in the ribbon at the top and click on ‘Conditional Formatting’.
- Select ‘Highlight Cells Rules’ and choose ‘Duplicate Values’ from the drop-down menu.
- You will see a pop-up window where you can select the formatting style for duplicate cells. Choose one that makes it easy for you to distinguish between them.
- Hit OK and let Excel do its magic. The tool will highlight all duplicate cells within your selected range.
- You can now sort or filter the results to see which columns/include heading/remove rows with duplicates, depending on your requirements.
It’s important to note that Excel’s built-in tools are really helpful, especially when dealing with large data sets containing numerous columns. Additionally, they help save time and boost productivity.
Pro Tip: When working with larger data sets, it’s best practice to use color coding or formatting options while highlighting duplicates, as it helps quickly locate identical entries within column ranges.
Formulas are like magic spells in Excel, except instead of turning someone into a toad, they help you identify duplicates.
Using formulas
By utilizing formulas, one can identify duplicates across multiple columns in Excel. A formula can help simplify the process of identifying duplicate entries, allowing for more efficient data management.
One way to use formulas to identify duplicates is by utilizing the COUNTIF function. By specifying the range of cells to check and the criteria for what constitutes a duplicate entry, Excel can quickly generate a count of duplicate entries.
Another useful formula is UNIQUE, which can be used to highlight or remove duplicate values from a list. This function allows you to easily clean up data sets by identifying and removing redundant or irrelevant information.
It is important to note that in order for these formulas to work effectively, your data set must be organized and structured properly. This means using consistent formatting conventions for each column and ensuring that all necessary information is included.
A study published on ScienceDirect found that the use of formulas in Excel significantly improves data accuracy and reduces errors.
Say goodbye to your duplicates, because we’re about to clean house like Marie Kondo on speed.

Excel formulas: Because manually finding duplicates is for chumps.
Using formulas
One effective way to eliminate duplicates in Excel is by using mathematical formulas. By utilizing the COUNTIF and IF functions, you can quickly identify and remove duplicated data points in your spreadsheet.
To use this method, first, select the column or range where duplicates may exist. Then, create an adjacent column and insert the formula =COUNTIF(A:A, A1)
(assuming that column A contains your data). This will highlight any cells with duplicate values.
Next, use the IF function to remove duplicates. Insert the formula =IF(B1>1,"Duplicate","Unique")
into another adjacent cell. This will indicate which values are unique and which are duplicate in separate columns.
Additionally, it is important to note that you can use variations of this formula to include multiple columns or ranges of data as well as conditionals such as case sensitivity.
By using formulas in Excel, you can easily identify and remove duplicates from your dataset while maintaining accuracy and efficiency.
