Hi,
Thanks for providing us the template files and sharing sample code.
After an initial test as  I have tested your sample code with your template Excel files. I have found the issue regarding font size which has changed a bit after the merging process is done. The font size in the first worksheet is fine but in the second worksheet, it extends the font size a bit as the you mentioned. I have logged a ticket with an id “CELLSNET-41842” for your issue. We will look into your issue soon.
Once we have any update on it, we will let you know here.
Thank you.

              Hi,
Well, it looks like rights issue, you have not sufficient rights to do that.
Anyways, another way is to uncheck “Keep this post private” checkbox (at bottom) when replying to this post if it works for your needs. Also, I cannot do this as you are the owner of your thread.
Thank you.
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              on reply also “Keep this post private”  is disabled for me.

              Hi,
   
Thanks for your posting and using Aspose.Cells for .NET.
We have fixed the issue.
Please download and try this fix: Aspose.Cells for .NET v7.5.1.2 and let us know your feedback.
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              Still the issue is partially solved.
If you review the page 2 of attached pdf then 4th row MISCELLANEOUS is not supposed to be Bold but coming bold in pdf. Which is fine in excel output.
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              Hi,
Thanks for the template files and the screen shot.
You are right, the issue is still there regarding bold font in the second worksheet of your attached template file when rendering to PDF file format. The original 4th row in the pivot table (in the second sheet of the template Excel file) is not bold where as it is rendered as bold in the output PDF (second page). I have reopened your issue “CELLSNET-41842” again. Our concerned developer will look into it soon.
Once we have any update on it, we will let you know here.
Thank you.
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              Hi,
Thanks for using Aspose.Cells.
Please add this sample code before saving:
C#
           for (int i = 0; i < book.Worksheets.Count; i++)
            {
                Worksheet sheet = book.Worksheets[i];
                if (sheet.PivotTables != null && sheet.PivotTables.Count > 0)
                {
                    for (int j = 0; j < sheet.PivotTables.Count; j++)
                    {
                        PivotTable table = sheet.PivotTables[j];
                        table.RefreshData();
                        table.CalculateData();
                    }
                }
            }
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              This all i have done and have in my code but still we are having this issue so please fix it from your side.
my code snapshot below
Dim pivot As Aspose.Cells.Pivot.PivotTable 
Dim pchart As Aspose.Cells.Charts.Chart 
''refreshing pivot tables and charts from all worksheets 
For Each ws As Aspose.Cells.Worksheet In myWorkBook.Workbook.Worksheets 
For Each pivot In ws.PivotTables 
pivot.PreserveFormatting = True 
pivot.RefreshData() 
pivot.CalculateData() 
Next For Each pchart In ws.Charts 
pchart.RefreshPivotData() 
Next 
Next
  
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              Hi,
It works fine and I don’t find the issue regarding bold font in the second worksheet of your attached template file when rendering to PDF file format. 
Here is my code and please find attached the output PDF file, all the pivot tables are rendered fine. 
Sample code:
[VB]
Dim wb As New Workbook(“e:\test2\PIVOT_78_0.xlsx”)
  For i As Integer = 0 To wb.Worksheets.Count - 1
				Dim sheet As Worksheet = wb.Worksheets(i)
				If sheet.PivotTables IsNot Nothing AndAlso sheet.PivotTables.Count > 0 Then
					For j As Integer = 0 To sheet.PivotTables.Count - 1
						Dim table As PivotTable = sheet.PivotTables(j)
						table.RefreshData()
						table.CalculateData()
					Next j
				End If
  Next i
 wb.Save(“e:\test2\PIVOT_78_0.pdf”)
If you still find the issue, kindly highlight the problematic areas in my attached PDF file comparing with the original file’s sheet(s), we will check it soon.
Thank you.
