If you have duplicate data in a workbook, it is good to be able to see what that duplicate data is, before deciding whether or not to delete it. In Microsoft Excel 2007 and Microsoft Excel 2010, conditional formatting can be used to search for duplicate records.
First select the data area for which you want to search for duplicate data.
On the Home tab, in the Styles group, click the Conditional Formatting dropdown, select Highlight Cells Rules, then click Duplicate Values. The Duplicate Values dialog box will be displayed.
From the values with dropdown, select your required formatting or click Custom Format, select your custom format, then click OK. Click OK. Cells containing duplicate values will be highlighted with your chosen formatting.
