Copying cell formula from one sheet to another sheet not working correctly

Hello,
I have 2 sheets and I want to copy formula from sheet1’s cell into sheets2’s cell.
ex.
Sheet1:
sheet1CellFormula = “=A10”;

and If I copy this formula into sheet2 cell, currently sheet2 cell formula is getting copied like this: “=A10” (which is incorrect, this way it is referring to A10 cell of sheet2 not sheet1),

It should refer to A10 cell of Sheet1 i.e. expected formula is =“Sheet1!A10”

Please suggest how to achieve this.

@ranishinde,

In MS Excel, when you perform the copy cell/formula from one sheet to another sheet manually, it works the same way. For your needs, you may try as following sample code:
e.g.
Sample code:

    Workbook workbook = new Workbook();
    //Get the first sheet (default)    
    Worksheet worksheet = workbook.Worksheets[0];
    //set formula
    worksheet.Cells["A1"].Formula = "=A10";
                
    //Add another sheet to workbook
    Worksheet sheet2 = workbook.Worksheets[workbook.Worksheets.Add()];
    //copy formula
    sheet2.Cells["A1"].Formula = worksheet.Cells["A1"].Formula.Insert(1, worksheet.Name + "!");

    workbook.Save("e:\\test2\\out1.xlsx"); 

Hope, this helps a bit.
