Excel interop - how to stop number (stored as text) being “evaluated”

Question

I was wondering if anyone had come across the following problem and had any ideas on how to resolve it: I\'m exporting data from a C# application (.NET 3.5) to Excel (2003)

Answer 1

I use this macro. It inserts an apostrophe before each value that is numeric in each cell.

Sub Macro1()
    Dim rwIndex As Integer
    Dim colIndex As Integer
    For rwIndex = 1 To ActiveSheet.UsedRange.Rows.Count
            For colIndex = 1 To ActiveSheet.UsedRange.Columns.Count
                If IsNumeric(Cells(rwIndex, colIndex).Value) Then _
                    Cells(rwIndex, colIndex).Value = "'" _
                     & Cells(rwIndex, colIndex).Value
            Next colIndex
    Next rwIndex
End Sub
