Created Unassigned: Replace a formula with its result [13326]

Hi,
I have an excel that is filled with formulas right through a second tab which is hidden, then I want my first tab shows the values in the cells, not the formulas or references from where the information is obtained.

I were trying using this __sheet0.GetRow(5).GetCell(1).SetCellFormula(null)__ but it sets the cell to null or empty and i need the value converted from the formula.

Thanks in advance
