为什么 Excel 宏将 - 识别为问号？

Question

I am trying to convert a column which has both positive and negative percentages into plain numbers. For example, -3.5% to 3.5. There is no problem converting positive percentage to simple numbers. For negative numbers though, result is showing as FALSE.

I suspect the problem is with this character at the beginning −0.27% and its different from the usual minus (-0.27%). How to write a macro to solve this problem?

Macro code:

ActiveCell.FormulaR1C1 = _
        "=IF(EXACT(LEFT(RC[-4],1),""""),RIGHT(RC[-4],LEN(RC[-4])-1)*-1*100,IF(EXACT(LEFT(RC[-4],1),0),RC[-4]*100))"

Answer 1

Replace − with - and then convert it.

Try

ActiveCell.FormulaR1C1 = "=ABS(SUBSTITUTE(RC[-4],""−"",""-""))"

Answer 2

Try

Sub Macro1()
   ActiveCell.Value = "=ABS(RC[-4])*100"
   ActiveCell.NumberFormat = "General"
End Sub

Answer 3

You don't need macro for this you can simply use the Excel's built in function ABS

Like below

=ABS(A2)*100

If you need to automate using VBA then also you can use the ABS function.
