Loading linux text file into excel using VBA

问题:

I have a text file created on linux, if I open it in Word pad the file appears normally. However when I open it in notepad, and when I try to load it into excel using the code below it appears as a single line.

' Open the file
Open Filename For Input As #1

' Look for the Table Title
Do While Not (EOF(1) Or InStr(TextLine, TableTitle) > 0)
    Line Input #1, TextLine
Loop

How can I split it into the original lines? Is there an end of line seperator, that vba can use?

回答1:

Linux uses a line-feed (\n) to denote a new line rather than the carriage return+line-feed (\r\n) as used by Windows so you can't use Line input, instead:

Open Filename For Input As #1
'//load all
buff = Input$(LOF(1), #1)
Close #1

'//*either* replace all lf -> crlf
buff = replace$(buff, vbLf, vbCrLf)
msgbox buff

'//*or* line by line
dim lines() As String: lines = split(buff, vbLf)
for i = 0 To UBound(lines)
   msgbox lines(i)
next

The Function

Public Function GetLines(fpath$) As Variant
    'REFERENCES:
    'Microsoft Scripting Runtime // Scripting.FileSystemObject
    'Microsoft VBScript Regular Expressions 5.5 // VBScript_RegExp_55.RegExp
    Dim fso As New Scripting.FileSystemObject, RE As New VBScript_RegExp_55.RegExp
    If fso.FileExists(fpath) = True Then
        Dim mts As MatchCollection, mt As Match
        Dim lines() As String
        Dim content$: content = fso.OpenTextFile(fpath).ReadAll()
        With RE
            .Global = True
            .Pattern = "[^\r\n]+" 'catch all characters except NewLines/Carraige Returns
            If .test(content) = True Then
                Set mts = .Execute(content)
                ReDim lines(mts.Count - 1)
                Dim pos&
                For Each mt In mts
                    lines(pos) = mt.Value
                    pos = pos + 1
                Next mt
            Else
                MsgBox "'" & Dir(fpath) & "' contains zero bytes!", vbExclamation
            End If
        End With
        GetLines = lines
    Else
        MsgBox "File not found at:" & vbCrLf & Dir(fpath), vbCritical
    End If
End Function

and could be invoked by (from immediate window)

?GetLines("C:\BOOT.INI")(2)

and the output

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

The above example could be used to get all lines from any text file originated from any OS.

Hope this helps.

Open the linux text file using Windows "Word Pad". Save the file. Word Pad will convert the linux line-feed (\n) to carriage return+line-feed (\r\n) as it saves the file. No coding is necessary.
