    Cool. That’ll be helpful when I need to change duplicate data.

    However, as long as you are only deleting the duplicate data, you can also simply use the “Remove Duplicates” function in the “Data” tab.

    Hi,

    Thanks for the information.
    It helped me alot.

    One query: Suppose I have 8000 Rows and I applied your method to find duplicates.
    After getting the cells highlighted, do we have option to check only highlighted rows..else I need to scroll down to find the highlighted cells

    Thanks

    Apply a filter to the column you are interested in. Click on the drop down list and you should see the option “Filter by Color”. Click on it and you can choose to “Filter by Cell Color”.
