creating pivot table using NPOI C#

Question

HI,

 

We are trying to create PivotTable using NPOI C# library on existing excel sheet by creating a new sheet.

 

The code executes fine, when we try to open the excel, it gives us following error:

 

Removed Part: /xl/pivotTables/pivotTable1.xml part with XML error. (PivotTable view) Load error. Line 2, column 561.

Removed Records: Workbook properties from /xl/workbook.xml part (Workbook)

 

 Any Help!!!
