Search in TXT file and return line to Excel

[jphumani]

Hi there to evereybody!

Im Juan and i'm writing from argentina.

I have a TXT file with millons o lines (literally) like this:

[FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]22082019;01092019;30092019;20000163989;D;S;N;0,00;0,00;00;00;ETCHEVERRIGARAY JUAN CARLOS

I would like to use a command button to search for the number i've marked with bold. In addition i'd like to recieve the entire line in Excel.

Basically each line contains some tax info for argentinian members.

I've seacher the web and tried something like this:

[FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]Function buscar()
Open "D:\caba.txt" For Input As #1
Do While Not EOF(1)
Line Input #1 , dato
If dato = UserForm1.TextBox1 Then
Range("b3").Value = UserForm1.TextBox1
Range("c3").Value = dato
End Function

Wish you can help me.

Thanks in advantage

Juan Pablo

I figured out another approach. First try it out with a small set of your data. About 15 identification numbers in column A, and keep your file with the one million lines small. Start with 100 lines to test. Otherwise Excel can freeze.

Option Explicit

Public Function QuickRead(FName As String) As Variant
    Dim i As Integer
    Dim res As String
    Dim l As Long
    Dim v As Variant

    i = FreeFile
    l = FileLen(FName)
    res = Space(l)
    Open FName For Binary Access Read As [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=i]#i[/URL] 
    Get [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=i]#i[/URL] , , res
    Close i
    
    'split the file with vbcrlf
    QuickRead = Split(res, vbCrLf)
End Function

Sub Find_Identification_Number()
    '[COLOR="#FF0000"]Replace file path/name to any file path/name you desire[/COLOR]
    Dim strFilePathName As String: strFilePathName = "[COLOR="#FF0000"]c:\temp\textfile.txt[/COLOR]"
    
    Dim strFileLine As String
    Dim myArr, v As Variant
    Dim LastRow, x, y As Long
    
    'Assume your Identification Numbers in Column A. Find last empty row.
    LastRow = Range("A" & Rows.Count).End(xlUp).Row
    
    'Store your Identification Numbers in Array myArr
    myArr = Application.Transpose(Sheets("Sheet1").Range("A2:A" & LastRow))
    
    'Counter for myArr
    y = 1
    
    'Read your file with the one million lines in Array v
    v = QuickRead(strFilePathName)
    
    'Process all Identification Numbers in Column A till there are no more left
    Do While y <= UBound(myArr)
        
        'Search for Identification Number in the lines from your file
        For x = 0 To UBound(v)
            If InStr(1, v(x), myArr(y)) > 0 Then
                
                'When found print to Immediate Window . . .
                Debug.Print myArr(y) & "->" & v(x)
                
                'Increase y to go to next Identification Number
                y = y + 1
                
                ' . . . and exit the for loop
                Exit For
            End If
        Next
    Loop
End Sub

Hello jphumani,

This problem is like the riddle "How do you eat an Elephant?". The answer: A piece at a time. The preferred method of handling large files is to do it in pieces or "chunks". A file chunk represents a range of data within a file. File chunking produces a list of chunks that are sequential and adjacent and that reference the entire contents of the file.

This macro will do just that. It will read up to 10,000 lines from the text file at a time. If there are fewer than 10,000 lines then the entire file is read. The lines are concatenated into a single string which is then searched for the word or phrase. Once found, the line of text it belongs to is extracted and returned by the macro. Because this macro is a UDF (User Defined Function) you can use this on a worksheet like a formula.

The default encoding for the text file is ASCII. If you have a text file that is "Unicode", or "UTF-8", simply add the encoding as a string to the macro call. It is the last argument.

First of all, as before, THANKS.

The only problema i have with your code is that i have the information in a TXT, its a line for each Tax Info of each person. And there are more tan 3 millons records

You can see a small sample on this link:

[FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]https://drive.google.com/open?id=1UzRBYKUF0LFlL3ibBI723FjKdXoXIZbC
[/FONT]
Oh, i've found this:

'Requires a reference to the Microsoft Scripting Runtime.
'Tools | References -> Microsoft Scripting Runtime
Excellent!

So, is there any modification i should make because im using a TXT file?

Please have a look at the file, its small.​

OK, first things first. I'm not the best coder so the code below is a little bit cumbersome but I hope it get's you going.

- Open your Visual Basic Editor with the shortcut Alt+F11. When you have a laptop you probably should give the shortcut Fn+Alt+F11. The Fn button on a laptop is called the function key and is used to activate a second function on the top buttons.
- In the top menubar click Insert and then choose Module.
- Copy and Paste the VBA code wich you can find below.
- To activate the red part:

'Requires a reference to the Microsoft Scripting Runtime.
'Tools | References -> Microsoft Scripting Runtime

click in the top menubar Tools and then References. Scroll through the very long list and search for "Microsoft Scripting Runtime" check the checkbox and click OK.
- Make adjustments to the path name in this line: Set txtStream = fspenTextFile("c:\temp\textfile.txt", ForReading, False). Point to the location where your text file is and you want to search.
- Return to your workbook.

Now you have to realize that we don't see your setup. How that looks like in your workbook. So we have to guess. You say: "So what i need to do is to search that identification number and calculate the exact tax for that person. Each state gives you a LARGE txt file with millons of "identification numbers".

Now let's assume that you have a bunch of your identification numbers in Column A of Sheet1 and run the code.

Hi Leith! Great response! Of course i understood the elephant thing haha.

Either im a Little stupid or either i couldn't make it happend.

I 've uploaded a sample of the TXT file and the Excel file with your codes. Something is wrong. Is there any chance you can have a look?

Hi Leith! allright! I've tested and...

With the sample, just fine.
With the complete file...i let it run about 1 hour and still "proccesing". So, maybe the file is to big for this code.

Could not solve it.

I wanted to let you know.

I had to make an adjustment if number was not found. Otherwise the Do While loop was infinite and Excel would hang/freeze.

I tested it with a large textfile with 500.000 lines. Took me about 5 seconds to process. Setup:
Identification Numbers in A2:A15 and one textfile with 500.000 lines.

Cave eat: pay special attention if line ending is vbLf (LineFeed) or vbCrLf (Carriage Return LineFeed). Red Part.

Hi there Strooman!

Ok, im not that intelligent...

You put me 2 codes. Where should i paste that? As a module? or in ThisWorkBook?

With this kind of code i wont use the "search button"?

I had to make an adjustment if number was not found. Otherwise the Do While loop was infinite and Excel would hang/freeze.

I tested it with a large textfile with 500.000 lines. Took me about 5 seconds to process. Setup:
Identification Numbers in A2:A15 and one textfile with 500.000 lines.

Cave eat: pay special attention if line ending is vbLf (LineFeed) or vbCrLf (Carriage Return LineFeed). Red Part.

Sub Read_Large_File()
    'Replace file path/name to any file path/name you desire
    Dim strFilePathName As String: strFilePathName = "c:\temp\textfile.txt"
    Dim strFileLine As String
    Dim myArr, v As Variant
    Dim LastRow, x, y As Long
    Dim blnFound As Boolean
    
    'Assume your Identification Numbers in Column A. Find last empty row.
    LastRow = Range("A" & Rows.Count).End(xlUp).Row
    
    'Store your Identification Numbers in Array myArr
    myArr = Application.Transpose(Sheets("Sheet1").Range("A2:A" & LastRow))
    
    'Counter for myArr
    y = 1
    
    'Read your file with the one million lines in Array v
    v = QuickRead(strFilePathName)
    
    'Process all Identification Numbers in Column A till there are no more left
    Do While y <= UBound(myArr)
        
        'Reset
        blnFound = False
        
        'Search for Identification Number in the lines from your file
        For x = 0 To UBound(v)
            If InStr(1, v(x), myArr(y)) > 0 Then
                
                'When found print to Immediate Window . . .
                Debug.Print myArr(y) & "->" & v(x)
                
                'Increase y to go to next Identification Number
                y = y + 1
                
                'Number found
                blnFound = True
                
                ' . . . and exit the for loop
                Exit For

        If blnFound = False Then
             
             'Number not found
             MsgBox ("Number" & myArr(y) & "not found")
            
            'Increase y to go to next Identification Number
            y = y + 1
            
        End If
    Loop
End Sub

Here is a function that I think should work (I did not download your file so I don't have a feel for how long it will take). Pass into the function the entire path to your text file and the value you want to find and it will return the entire line of text that value is on...

Function GetEntireLine(FullPath As String, GetWhat As String) As String
  Dim FileNum As Long, Position As Long
  Dim TotalFile As String
  FileNum = FreeFile
  Open FullPath For Binary As [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=FileNum]#FileNum[/URL] 
    TotalFile = Space(LOF(FileNum))
    Get [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=FileNum]#FileNum[/URL] , , TotalFile
  Close [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=FileNum]#FileNum[/URL] 
  TotalFile = vbNewLine & TotalFile & vbNewLine
  Position = InStr(TotalFile, GetWhat)
  GetEntireLine = Mid(TotalFile, InStrRev(TotalFile, vbNewLine, Position) + 1, InStr(Position, TotalFile, vbNewLine) - InStrRev(TotalFile, vbNewLine, Position))
End Function

You put me 2 codes. Where should i paste that? As a module? or in ThisWorkBook?

You can paste both macro's in a standard module.

With this kind of code i wont use the "search button"?

This is correct. I didn't implement a search button. Just put some Identification Numbers in column A (starting in A2) and adjust the file path and point to your file with all those lines you want to search. The result will be printed to the Immediate window of the Visual Basic Editor. This is just a basic setup to see if everything is working correctly.
