Converting to ASCII Text

by Allen Wyatt
(last updated June 19, 2018)


Brenda has a lot of information that has been imported or pasted into a worksheet. Sometimes the text in the worksheet will contain "foreign" and strange characters. She wonders if there is a way to easily convert the data so that it contains no non-ASCII characters and, perhaps, some foreign characters are converted to regular ASCII values (such as converting accented letters to non-accented letters).

There are a couple of things you can try. First, you can use the CLEAN worksheet function to get rid of non-printable characters. Just use the function in this manner:


The result is "cleaned" text, without the non-printables. If you want to replace foreign characters with regular ASCII characters, that will need to be done with a macro. Here's an example of a relatively straightforward approach:

Sub StripAccent()
    Dim sAcc As String
    Dim sReg As String
    Dim sA As String
    Dim sR As String
    Dim i As Integer

    sAcc = "ŠŽšžŸÀÁÂÃÄ�...ÇÈÉÊËÌÍÎÏÐ�'�'�"�"ÕÖÙÚÛÜÝàáâãäåçè�©êëìí�®ïðñòóôõöùúûüýÿ"
    sReg = "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy"

    For i = 1 To Len(sAcc)
        sA = Mid(sAcc, i, 1)
        sR = Mid(sReg, i, 1)
        Selection.Replace What:=sA, Replacement:=sR, _
          LookAt:=xlPart, MatchCase:=True
End Sub

The macro steps through the characters in the sAcc variable and, one at a time, uses Find and Replace to replace them with the corresponding character in the sReg variable. You can adjust the contents of sAcc and sReg to reflect your conversion needs; the key is to make sure that they are both the same length.

If you want to do it with a UDF this smaler function will do it much faster since it has only one loop:

Function StripAccent(sText As String) As String
Dim X As Integer, Y As Integer
Const sAcc = "ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÓÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðñòóôõöùúûüýÿ"
Const sReg = "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy"
For X = 1 To Len(sText)
Y = InStr(sAcc, Mid(sText, X, 1))
If Y Then Mid(sText, X, 1) = Mid(sReg, Y, 1)
Next X
StripAccent = sText
End Function

The following will replace foreign characters in a cell.

In a module place this code:

Function funcStripAccent(strText As String) As String

Dim sAcc As String
Dim sReg As String

Dim intInner As Integer
Dim intOuter As Integer

sAcc = "ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÓÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðñòóôõöùúûüýÿ"
sReg = "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy"

For intOuter = 1 To Len(strText)

For intInner = 1 To Len(sAcc)

If Mid(strText, intOuter, 1) = Mid(sAcc, intInner, 1) Then
Mid(strText, intOuter, 1) = Mid(sReg, intInner, 1)
End If

Next intInner

Next intOuter

funcStripAccent = strText

End Function

Assuming that the foreign text is in A1 then in the destination cell enter: =funcStripAccent(A1)
This can be fllled to other cells as required.

As mentioned, sAcc and sReg must be the same length with matching conversion characters.

The macro in this tip is really sloppy work. When you copy and paste it in VBA the "sAcc = ..." row gets entirely blood red meaning there is an error. This is because at 2 places in the string there is a single quotation mark which is not allowed . When you remove them you can run the macro but it replaces all the characters in the selected text with an o (ooooooo...)!!!.

Obviously the sAcc and sReg strings should be exactly the same length which is not the case here. The sAcc string is much longer and contains beside the 2 quotation marks a dozen of useless characters including some question marks. These causes the erroneous result. The last question mark in the sAcc string corresponds to the letter o in the sReg string so when sA contains a ? , Replace considers this as a wild card and replaces all the characters in the selection with an o which is the content of sR at that moment.

Here is my version of the macro (smaler as usual :-) that does the job properly:

Sub StripAccent()
Const sAcc = "ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝàáâãäåçéèêëìíîïðñòóôõöùúûüýÿ"
Const sReg = "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeeiiionooooouuuuyy"
Dim X As Integer
For X = 1 To Len(sAcc)
Selection.Replace _
What:=Mid(sAcc, X, 1), _
Replacement:=Mid(sReg, X, 1), _
LookAt:=xlPart, MatchCase:=True
End Sub
