Highlight Duplicates Except First Number in Range in Microsoft Excel

In this article, we will learn Highlight Duplicates Except First Number in Range in Microsoft Excel.

Scenario :

Earlier we learned how to highlight the entire if any cell in row contains specific text. Now we will learn how to separate duplicate values where the first occurrence is considered as a unique value. For example: In an array of 1 , 2 , 3 , 1 , 4 & 5 , Only the 1 at 4th number will be coloured differently. Separation is done on the basis of cell format. So we know conditional formatting is our tool.

we will highlight the row using conditional formatting.

Generic Formula in Conditional Formatting

= COUNTIF ( $R$1:R1  , >1)

Cell with relative row: this is a cell reference where the column is absolute and row is relative. For example $A$1 (fixed row and column) and $A1 (fixed row) and A$1 (fixed column) . Learn in detail about referencing in excel here.

> 1 : It is the criteria that you want to match and highlight.

Example :

All of these might be confusing to understand. Let's understand how to use the function using an example. Here I have some data on fruits. I just want to highlight the entire row if the fruit rate is greater than 100.

Select the row of table (A2:C2).

  1. Go to conditional formatting and click on the new rule. You can use a sequential shortcut ALT>H>L>N.
  2. Select “use a formula to determine which cell to format”.
  3. Write this formula.

It is necessary to select the entire row before doing conditional formatting.

  1. Click on format and choose any color in fill. Hit ok.

Copy this range and paste the special format to the entire table.

Now each cell will be highlighted whose frequency or occurance is greater than 1. Here I have hardcoded the criteria, but you can give cell reference too.

How does it work?

Well, it is quite simple. Here the formula just colours the cell where count of value comes greater than 1. In the first occurrence of the value, the count remains 1.

Note that only the cell $D$2 is frozen using $ and row are left relative. It is because we want to change the lookup row when we copy the conditional formatting and the column stands absolute. In the end we get highlighted cells that contain values greater than 1. Learn about referencing in detail here.

So yeah guys, this is how you can highlight the entire row based on cell value or criteria. This is quite easy if you understand absolute and relative referencing in excel.

Here are all the observational notes regarding using the formula.


  1. Conditional formatting allows you to apply the formatting basis on the cell values such as colours, icons and data bars.
  2. The formula works for text and numbers both.
