Once dupes are identified, you can turn on Excel Filter to display only repeated values.For text values, the formulas are exactly the same :) In this example, we were dealing with duplicate numbers.In B3, the range expands to $A$2:$A3, so the value in A3 is compared against the above cell as well, and so on. So, the formula in B2 compares the value in A2 only against this cell itself. When copied to the below cells, the range reference expands by 1. For this, build an expanding range reference like $A$2:$A2. To get duplicate cells without first instances, you compare the target cell (A2) only with the above cells, not with each other cell in the range. This formula goes to B2, and then you copy it down to as many cells as there are items in the list. To locate duplicate cells including first instances, you compare the target cell (A2) with all other cells in the range $A$2:$A$10 (notice that we lock the range with absolute references), and if more than one cell containing same value are found, label the target cell as "Duplicate". IF(COUNTIF( expanding_range, cell)>1, "Duplicate", "")Īs you can see, the formulas are very much alike, the difference is in how you define the source range. Click the Format… button and choose the formatting options you like.The detailed explanation of the formula is provided in a separate tutorial. Where B2 is the first cell in the first column, B7 is the last cell in the first column, and A2 is the cell in the blank column corresponding to the first row in your selected range. In the Format values where this formula is true box, enter the following formula:. On the Home tab, in the Styles group, click Conditional Formatting > New rule > Use a formula to determine which cells to format.To create a rule, these are the steps to perform: The formula is quite tricky and requires adding a blank column to the left of your dataset (column A in this example). To mark duplicate values except 1 st instances, the inbuilt rule cannot help, and you'll need to set up your own rule with a formula. Highlight duplicate cells except first occurrences To highlight unique cells, pick Unique in the left-hand box.Įxample 2.To apply your own formatting for duplicates, click Custom Format… (the last item in the drop-down list), and then choose the desired Font, Border and Fill options.Excel will show you a preview of the selected format right away, and if you are happy with it, click OK. In the Duplicate Values pop-up dialog, choose formatting for Duplicate cells (the default is Light Red Fill and Dark Red Text).On the Home tab, in the Styles group, click Conditional Formatting > Highlight Cells Rules > Duplicate Values….Select a range where you want to find duplicate cells.To apply the built-in rule for duplicates, perform these steps: As you can understand from the heading, this rule highlights all occurrences of a duplicate value, including the first one. In this example, we will be using a preset rule available in all versions of Excel. Highlight duplicate cells including first occurrences The below examples illustrate both cases. In a simplest case, you can apply the predefined rule in more sophisticated scenarios, you will have to create your own rule based on formula. To highlight duplicate values in a column or range, you normally use Excel Conditional Formatting.

The TOCOL function lets you combine multiple cell ranges by adding parentheses and commas as delimiting characters. The TOCOL function rearranges values in 2D cell ranges to a single column.įunction syntax: TOCOL(array,, ) Explaining the formula in cell H3 Step 1 - Combine cell ranges You are not limited to three cell ranges, you can use up to 254 cell ranges.
