I am writing some code where I import some files under TMX (a form of xml).
I tried various options
a) using the Open FileName For input, but this messes up the character encoding
b) opening the file and copying the data using the msoDialog, but this return an error if the file is too large (which is often the case) and this put the data in an utterly messy manner.
c) opening the file using notepad, but there are the same limitations in so far as copying the entirety of the file into Excel as the previous option.
I am not trying to use a shell function calling onto Wordpad.
My issue right now, is that I need to copy the file line by line to treat its content according to my needs (hopefully without losing the character encoding
Would someone know how to copy every single line from the file opened in WordPad and paste it post treatment (selection of the relevant elements) into Excel?
Thank you
For large files you can use this solution:
Public Sub ImportTMXtoExcel()
Call Application.FileDialog(msoFileDialogOpen).Filters.Clear
Call Application.FileDialog(msoFileDialogOpen).Filters.Add("TMX Files", "*.tmx")
Application.FileDialog(msoFileDialogOpen).Title = "Select a file to import..."
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False
intChoice = Application.FileDialog(msoFileDialogOpen).Show
If intChoice <> 0 Then
strFileToImport = Application.FileDialog(msoFileDialogOpen).SelectedItems(1)
Else
Exit Sub
End If
intPointer = FreeFile()
Open strFileToImport For Input Access Read Lock Read As #intPointer
intCounter = 0
Do Until EOF(intPointer)
Line Input #intPointer, strLine
intCounter = intCounter + 1
Worksheets(1).Cells(intCounter + 1, 1).Value2 = strLine
Loop
Close intPointer
End Sub
For other encodings you can use ADO's Stream as described in this solution:
VB6/VBScript change file encoding to ansi
If you have large files which require ADO's Stream then you might want to consider breaking down the large files first as described in this solution:
How to split a large text file into smaller files with equal number of lines?

I have a text file that is automatically generated from a machine. The machine writes the txt file in "chunks" (sorry I don't know the exact terminology). I need to pull data from this txt file, but I need the txt file to be finished before pulling data from it. I found a solution to verify that the machine has finished writing to the file... It is not as elegant as i had hoped, but seems to do the trick. Excel VBA opens a command prompt, the command prompt uses a Find command to find the string "End of Report"... This is basically one of the last lines of the txt file and pretty safe to assume the txt file is finished after this is found. This code runs in a loop 1000 times, every 10 seconds, until it finds this string or reaches 1000 tries...
The issue is that "result" returns some other characters besides just "End of Report" this is further complicated by the fact that I am attempting to run this on some csv files too... and "result" returns some additional characters also, but different from the ones returned from the txt files. For example, if I check the length of "result"... The length comes back as 43 on one file and 48 on another file... I think it is counting the file path + "End of Report" + a few more characters?
Anyways, I don't really need the "result"... I really only need a "true" / "false" if "Find" found "End of Report" or not... How can I accomplish this? Is there a different better way to do this? I am not familiar with command prompt programming.
Note: It is important that I search these files without opening them.
Sub test()
Dim SearchStr As String
Dim cmdLine As Object
Dim result As String
Dim FilePath As String
FilePath = "D:\test2.txt"
SearchStr = """End of Report"""
Set cmdLine = CreateObject("WScript.Shell")
result = cmdLine.Exec("%comspec% /C Find " & SearchStr & " " & Chr(34) & FilePath & Chr(34)).STDOut.ReadAll
Debug.Print (result)
End Sub
I am not really an expert in command line, but what I would do is export the result of the FIND command to a file, like here
Then I would check in your VBA code how many rows are in the file (either clean the file before, or check the number of rows before the export is done).
If the number of rows meets the criteria (probably 2 or more rows instead of 1), then you can set the flag to True.
Exported text files from Excel are encoded with UTF-8.
An encoding UTF-8-BOM is needed.
I think that in code shall be inserted a row, written like:
Java
?xml version="1.0" encoding="UTF-8"?
Jasperreport CSV UTF-8 without BOM instead of UTF-8
or
HTML5
meta charset="utf-8"
Bad UTF-8 without BOM encoding
Sub export_data()
Dim row, column, i, j As Integer
Dim fullPath, myFile As String
fullPath = "C:\Workspace"
row = 21
column = 5
For i = 1 To column
myFile = Cells(1, i).Value + ".txt"
myFile = fullPath + "/" + myFile
Open myFile For Output As #1
For j = 2 To row
Print #1, Cells(j, i).Value
Next j
Close #1
Next i
End Sub
How can I define and where to put a row, which defines encoding UTF-8-BOM?
Thank You.
Instead of Printing the file line by line, it might be more efficient to
save your selected range as a CSV UTF-8
you might need to change the file type after saving
Use ADO to process the file as UTF-8
Either will add a BOM automatically.
EDIT
If you are unfamiliar, you could perform the save to csv - utf8 process manually with the macro recorder turned on. Then examine what you have recorded and make appropriate edits.
Another way of adding the BOM, in the context of your existing code, would be to write it directly as a byte array to the first line.
For example:
Dim BOM(0 To 2) As Byte 'EF BB BF
BOM(0) = &HEF
BOM(1) = &HBB
BOM(2) = &HBF
Open myFile For Binary Access Write As #1
Put #1, 1, BOM
Close #1
will put the BOM at the beginning of the file.
You should then change the mode in your subsequent Print code to Append.
I suggest you read about the pros and cons of using Print vs Write
You should also read about declaration statements. In yours, only the last variable on each line is being declared as the specified type; the preceding variables are being implicitly declared as being of type Variant.
I am trying to open a file with a Unicode file name for binary access to calculate the MD5 check sum. I have the file names and path stored in a excel sheet correctly.
File Names Used:
The code then fails atOpen sPath For Binary Access Read As lngFileNumber with 'Run-Time error'52': Bad file name or number
Function GetFileBytes(ByVal sPath As String) As Byte()
' makes byte array from file
Dim lngFileNum As Long, bytRtnVal() As Byte, bTest
lngFileNum = FreeFile
If LenB(Dir(sPath)) Then ''// Does file exist?
Open sPath For Binary Access Read As lngFileNum
'a zero length file content will give error 9 here
ReDim bytRtnVal(0 To LOF(lngFileNum) - 1&) As Byte
Get lngFileNum, , bytRtnVal
Close lngFileNum
Else
Err.Raise 53 'File not found
End If
GetFileBytes = bytRtnVal
Erase bytRtnVal
End Function
Any suggestions?
You can make the filename "acceptable" by converting it with the StrConv function. I tried your code with this modification:
Open StrConv(sPath, vbUnicode) For Binary Access Read As #1
...and the Open command ran successfully with my test filename abc✓✘.mp3. I can't say for sure if it would works with yours since you included them as an image, but it should be okay.
Unrelated:
The next line (Redim...) has a different problem for you to debug. (Perhaps you can't use LOF with this type of file? or maybe use FileLen instead?.)

I have a large text file exported from an application that has three unwanted zeros in each row. The text file needs to be imported into another application and the zeros cause a problem.
Basically the unwanted three zeros per row need to be deleted. These zeros are always in the same location (same number of characters when counting from the left), but the location is somewhere in the middle. I have tried various things like importing the file into excel, removing the zeroes and then exporting as text file, but always have formatting problems with the exported text file.
Can someone suggest a solution or point me in the right direction?
something like this ? (quickly done)
Sub replaceInTx()
Dim inFile As String, outFile As String
Dim curLine As String
inFile = "x:\Documents\test.txt"
outFile = inFile & ".new.txt"
Open inFile For Input As #1
Open outFile For Output As #2
Do Until EOF(1)
Line Input #1, curLine
Print #2, Replace(curLine, "000", "", 6, 1, vbTextCompare)
Loop
Close #1
Close #2
End Sub
Alternatively, you can do that with any text editor that allows block selection (I like Notepad2, tiny, fast and portable)
I see you use excel a lot.
When you import the text file into excel do you use the import function and do you push the data into separate cells?
if the cell is numeric you could do the following:
=LEFT(TEXT(G5,"#"),LEN(TEXT(G5,"#"))-3)
if the cell is text:
=LEFT(G5,LEN(G5)-3)
G5 would the cell the data row/field is in.
curLine = Left(curLine, 104)
This will take the first 104 characters
Before all, I want to say that I am not a programmer, so this may be basic for some people but surely not for me!!
The task that I want to accomplish is to retrieve some characters of a data file that is imported automatically from a server.
Data is stored in lines in a CSV or tabbed .txt file, each line consists of date and some numeric values. The format is always the same, only the file grows in one line each time a new value is entered.
What I need the script to do, is open that file (wich adress is known and constant) search for the last line, and then extract a string from that line and write it on a different .TXT file, from where I can import it to another specific software as a raw value.
The part in the middle (extracting string) is fairly simple, but opening and isolating the last line is far too much for me.
Thanks everybody for helping!
