Cannot implicitly convert type 'object' to 'Microsoft.Office.Interop.Excel.Worksheet'. An explicit conversion exists (are you missing a cast?)

Answer 1

To resolve your second error,

//Error at .Value2

1. Go to project properties. (Click Project in Menu, Click properties)
2. Set the Target Framework as .NET Framework 4
3. This should resolve your .Value2 error.

Answer 2

you have to create a new Worksheet with Sheets array by providing WorkSheet Name. and also please Cast The Newly Created WorkSheet.

Replace this :

Excel.Worksheet sh = wb.Sheets.Add();

with following

 Excel.Worksheet sh  = (Microsoft.Office.Interop.Excel.Worksheet)wb.Sheets["Sheet1"];
