I have this Excel archive with 5 columns of data, and then, about 4,000 rows of different data for each column, but I can’t find a way to make that Excel marks the repeated rows?

Excel I have tried using the Conditional Formating Rules, but it only marks the repeated cells, not rows.


You could try applying the concatenate function before using conditional formatting. http://blog.contextures.com/archives/2013/04/11/highlight-duplicate-records-in-an-excel-list/

  • Thank you so much, that Concatenate formula is awesome :D – Victor F Salazar G Dec 3 '14 at 5:46

Go back to Conditional Formatting and delete any prior rules you have created for this purpose, then (full columns A:H selected) create a new rule using the option to Use a formula to determine which cells to format. Supply the following to the Format values where this formula is true textbox:


You likened your requirement to the existing Format only unique or duplicate items options so I assumed that you wanted both the first and any subsequent duplicates highlighted.

Caveat: If you have more than ~1000 rows then you may experience some latent calculation lag. This could be reduced with a helper column holding a concatenated value as mentioned in the previous reply. Which method you choose will depend upon the number of row within the conditional formatting rule's Applies to: region and what you feel you can live with.
