Replace nth/all occurrences of a character in string in Excel

This method will introduce the easy SUBSTITUTE function to replace the nth or all occurrences of a certain character in a cell in Excel.

Select a blank cell, and type the formula =SUBSTITUTE(A1,"o","_",3) into it, and press the Enter key. See screenshot:

And now you will see the third “o” is replaced. See screenshot:

(1) In the formula =SUBSTITUTE(A1,"o","_",3), A1 is the cell you will replace string, o is the specified character you will replace, _ is the specified character you will replace with, and 3 means you will replace the 3rd occurrence of “o”.
(2) If you need to replace all occurrences of “o” with underline in the Cell A1, please apply this formula =SUBSTITUTE(A1,"o","_").

Как из ячейки с текстом "5x50x100" извлечь произведение всех чисел в другую ячейку чтобы был результат 25000?

Hi there,

We've created a VBA to help you solve the problem. In your Excel, please press Alt + F11 to open the VBA window, and then on the Insert tab, click Module. And copy and paste the VBA below into the window:
Function ExtractAndMultiply(xCell As Range) As Long
    'Update by ExtendOffice
    Dim xNum As Long
    Dim xBool As Boolean
    xNum = 1
    xBool = False
    xArr = Split(xCell.Value, "x")

    For i = LBound(xArr) To UBound(xArr)
        If IsNumeric(xArr(i)) Then
            xNum = xNum * xArr(i)
            xBool = True
        End If
    If xBool Then
        ExtractAndMultiply = xNum
        ExtractAndMultiply = 0
    End If
End Function

Now, you can go back to the worksheet, and let's say the cell A1 contains 5x50x1000, you can enter the formula =ExtractAndMultiply(A1) in another cell to get the product.

I use Office 2013 and last parameter doesn't work as intended. I didn't specify it but it works like 1 entered.Only first occurence is replaced.

Hi Turker,
To replace all of a certain character from a cell, you need to apply this formula =SUBSTITUTE(A1,"o","_")
