Focus is not setting in first cell in all the worksheet

I have an empty excel template with multiple sheets. In all the sheets, I have placed the cursor in A1 cell and saved the work book.
Data is populated in the template using c# code and when downloading it, I can see the focus is not set to A1 cells in all the work sheets.

workbook is saved as below in c# code:
MemoryStream memoryStream = new MemoryStream();
if (extension == “.xlsx”)
workBook.Save(memoryStream, SaveFormat.Xlsx);
else if (extension == “.xlsm”)
workBook.Save(memoryStream, SaveFormat.Xlsm);
memoryStream.Seek(0, SeekOrigin.Begin);
Empty template:

Downloaded excel after populating data:

Do I have explicitly set the focus for each worksheet? what function of aspose cell can be used?

@ramyaraj10,
Please use the following code to set the focus cell:

Worksheet.ActiveCell = "A1";

@ramyaraj10
Also you can select range as the following codes:

 Workbook workbook = new Workbook(dir + "book1.xlsx");
            Worksheet sheet = workbook.Worksheets[0];
            //Worksheet sheet =  workbook.Worksheets.RevisionLogs.ListOnANewSheet();
      
            sheet.SelectRange(0, 0, 1, 1, true);
            //if you want to change first visible cell
            //sheet.FirstVisibleRow = 4;
           // sheet.FirstVisibleColumn = 2;
            workbook.Save(dir + "dest.xlsx");
