Hello Karan,
sometime having multiple versions of same jar (xmlbeans ,poi.ooxml ) in the classpath can cause such issue.
Chek this jar in userlib folder and keep the highest version and remove duplicate and other version.

Hi Karan,
Check this column CTPivotCacheDefinition, either this column is not available in excel or it is not properly mapped to the attribute.
There could be also a possibility that the data is not as per the rules defined for that attribute in Template.
