Question

I just ran a Macro and got the below:

Sub Macro1()
'
' Macro1 Macro
'

'
    Columns("B:B").Select
    Range("B4").Activate
    Selection.NumberFormat = "0.00"
    Selection.NumberFormat = "@"
End Sub

Now couldn’t understand the difference between Selection.NumberFormat = "0.00" and Selection.NumberFormat = "@" Can you help me to understand the same?

I was also trying to convert some number as text in Excel into number. What would be good syntax to do so?

EDIT

I tried to convert all numbers which is stored as text to number by the below,but nothing changed. Please guide if I am wrong:

objSheet1.Columns(11).NumberFormat = "0"

Answer 1

Is this what you are trying?

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long, i As Long

    '~~> Change this to the relevant sheet name
    Set ws = ThisWorkbook.Sheets("Sheet1")

    With ws
        '~~> Col B
        .Columns(2).NumberFormat = "0.00"

        '~~> Get the last row
        lRow = .Range("B" & .Rows.Count).End(xlUp).Row

        For i = 1 To lRow
            .Range("B" & i).Formula = .Range("B" & i).Value
        Next i
    End With
End Sub
