Find the current user language

        End If
    Next htmlCell

End Function

My initial code (utilising this vbforum code) assumed that Windows and Excel share a common language - likely but not bulletproof.

updated

The revised code:

1. Returns the Locale ID (LCID).
2. Looks up the LCID from this msft link.
3. Parses the LCID using a regexp to get the language.

Sample output on my machine below

The code will let the user know if there are any errors in accessing the LCID website, or in parsing the country name.

    Sub GetXlLang()
        Dim lngCode As Long
        lngCode = Application.LanguageSettings.LanguageID(msoLanguageIDUI)
        MsgBox "Code is: " & lngCode & vbNewLine & GetTxt(lngCode)
    End Sub

    Function GetTxt(ByVal lngCode) As String
        Dim objXmlHTTP As Object
        Dim objRegex As Object
        Dim objRegMC As Object
        Dim strResponse As String
        Dim strSite As String

        Set objXmlHTTP = CreateObject("MSXML2.XMLHTTP")
        strSite = "http://msdn.microsoft.com/en-us/goglobal/bb964664"

        On Error GoTo ErrHandler
        With objXmlHTTP
            .Open "GET", strSite, False
            .Send
            If .Status = 200 Then strResponse = .ResponseText
        End With
        On Error GoTo 0

        strResponse = Replace(strResponse, "</td><td>", vbNullString)
        Set objRegex = CreateObject("vbscript.regexp")
        With objRegex
            .Pattern = "><td>([a-zA-Z- ]+)[A-Fa-f0-9]{4}" & lngCode                    
            If .Test(strResponse) Then
                Set objRegMC = .Execute(strResponse)
                GetTxt = objRegMC(0).submatches(0)
            Else
                GetTxt = "Value not found from " & strSite
