VBA Issue with Number formatted as text when numbers include comma - excel

Question

I use a vba script to open another workbook. This workbook is in format .XLS and the content from a DB was stored like:
"Name1" "0" "7,98"
"Name2" "5" "1"
"Name3" "2" "7,1"
When opening the workbook with a VBA script, every cell that includes a comma, is interpreted as text and shows this warning:
The number in this cell is formatted as text or is preceded by an apostrophe
Strangely, if I open the file by double clicking, the numbers are just formatted as text and don't show any error. I guess, Excel is doing some interpretting, which doesn't work.
My code is:
Dim WorkBookImport As Workbook
Name = Application.GetOpenFilename()
If Name <> False Then
Set WorkBookImport = Workbooks.Open(Filename:=Name)
End If
I tried everything from:
Range(mycolumn).Value = Range(mycolumn).Value
For loop with CDbl(.Value)
Range(mycolumn).TextToColumns ...
Nothing works ;( Please help!

Answer 1

Option Explicit
Sub edksg()
Dim c As Range
Set c = Sheet1.Range("D3")
c.Value2 = CDbl(c.Value2)
End Sub
Works fine for me when cell D3 of the worksheet is formatted as text.
Of course, my location uses the comma as decimal separator, so if your location uses a different standard, the issue might be there. In that case, doing something like CDbl(Replace(c.Value2, ",", Application.DecimalSeparator, 1, -1, vbBinaryCompare)) might solve that part of the issue.
If you want to loop through the entirety of some column, the end result might look something like this, assuming the values you want to convert to numbers are in column C.
Option Explicit
Sub edksg()
Dim c As Range
Dim r As Range
Set r = Sheet1.Range("C1:C" & Sheet1.Range("C" & Sheet1.Rows.Count).End(xlUp).Row)
For Each c In r
If Len(c) > 0 Then
c.Value2 = CDbl(Replace(c.Value2, ",", Application.DecimalSeparator, 1, -1, vbBinaryCompare))
End If
Next c
End Sub

It´s a problem with the formating of the cells. You should use NumberFormat to change it.
Sub FormatNumber()
ThisWorkbook.Worksheets("YourWorkbook").Range("YourRange") = CDbl(ThisWorkbook.Worksheets("YourWorkbook").Range("YourRange"))
ThisWorkbook.Worksheets("YourWorkbook").Range("YourRange").NumberFormat = "General"
End Sub
With NumberFormat you can also change it to text if you have the opposite problem, in this case you would use NumberFormat = "#"
