How many bytes per row of data in Excel RRS feed

  • Question

  • Hi folks,

    I have million rows of data and I'm trying to size each row that comes with 30 columns which are a mix of numerical and text characters. Is there a formula anyone can share that I can use in my Excel file to calculate the total byte size of each row so I can add them up for the million rows to see what am I dealing with? Thanks so much!

    I've made a macro (not Formula in cells).

    [VBA code]
    Sub Count_Bytes()
        Dim totalBytes As Long: totalBytes = 0
        Dim lastRow As Long
        ' --- assuming there is no blank cell before the last cell in column A
        lastRow = Cells(Rows.Count, 1).End(xlUp).Row
        ' ---
        Dim r, c As Long
        For r = 1 To lastRow
            For c = 1 To 30
                totalBytes = totalBytes + Len(Cells(r, c).Value)
            ' ---
            MsgBox "Row = " & r & " -- total bytes = " & totalBytes
    End Sub
    If you want to put the total bytes of each row instead of using MsgBox, please put them in another sheet.
