How to Resolve Duplicate Data within Excel Pivot Tables

Notice that most rows show TRUE, but in two instances it shows FALSE. This signifies that the account numbers on rows 3 and 7 are stored as text. This nuance explains why Pamela’s pivot table was reflecting duplicate data. 
If you wish to recreate this scenario, add an apostrophe before one or more account numbers to convert the number to text. Make sure that you leave at least one instance of the account number as a value. Right-click on your pivot table and choose Refresh to make the duplicate values appear.
Should you encounter this situation in the future, an easy fix is shown in Figure 5:
In any version of Excel: Select column A, choose Data, Text to Columns, and then Finish.

Next return to your pivot table, right-click any cell within it, and choose Refresh. The duplicate values should vanish from your pivot table, as shown in Figure 6.
