VBA number formatting (with commas as decimal separator) - excel

Question

The main problem started when I wanted to "convert to number" by the green triangle (I know I can do it by hand, but there are a lot of cells like that and in the future I only want to use code).
So I wanted to do it by code, and I came across with this code that helps, but I have a problem with the number format which removes the decimal numbers.
Sub Valor3()
Dim LastRow As Long, i As Long
LastRow = Sheets("Hoja3").Range("A" & Rows.Count).End(xlUp).Row
'Sheets("Hoja3").Range("A1:A" & LastRow).NumberFormat = "# ##0,00"
For i = 1 To LastRow
If Val(Sheets("Hoja3").Range("A" & i).Value) <> 0 Then _
Sheets("Hoja3").Range("A" & i).Formula = _
Val(Sheets("Hoja3").Range("A" & i).Value)
Next i
End Sub
I've been trying many formats but none of them seems to help.
It might be because here we use the comma as a decimal separator and there is no miles separator.
What number format would help me?

Answer 1

The issue is that you use Val function in combination with a non-us-english decimal separator, which is not a proper solution to your issue.
The Val function recognizes only the period ( .) as a valid decimal separator. When different decimal separators are used, as in international applications, use CDbl instead to convert a string to a number.
Source: Microsoft documentation Val function.
Since the Val function does not convert a text into a value but extracts
The Val function only works with a dot . as decimal separator.
Example:
Val("2.55") 'will return 2.55 as number
Val("2,55") 'will return 2 as number (because it cuts off all text and the comma is not considered as decimal separator)
To get rid of the green triangle and convert a number that is saved as text into a real number properly, use the following:
Option Explicit
Public Sub ConvertNumberAsTextIntoRealNumber()
Dim ws As Worksheet
Set ws = ThisWorkbook.Worksheets("Hoja3")
Dim LastRow As Long
LastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
With ws.Range("A1", "A" & LastRow)
.NumberFormat = "# ##0.00" 'set your desired number format
.Value = .Value 'this will in most cases already convert to real numbers.
End With
'But if your numbers are hard coded to text and begin with a `'` you need the following additionally:
Dim iRow As Long
For iRow = 1 To LastRow
With ws.Cells(iRow, "A")
If IsNumeric(.Value) Then 'can the value be interpreted as a number
If .Value <> 0 Then 'is the value not zero
.Value = CDbl(.Value) 'then convert it into a real number
End If
End If
End With
Next iRow
End Sub

I know you are looking for VBA solution, but here's a small Excel trick that you might find useful:
Enter 1 (numeric value) somewhere in the file and copy it:
Select your range (A1:A6) and go to Paste > Paste Special > select Multiply:
The final result is all your text values being converted to numbers:
The same trick will work with other combinations, e.g. Operation: Add while having 0 copied, etc.
