how can i use a macro to remove duplicate lines in my text file such that the last one will remain, for instance
the boy is good
great thinking
great thinking
he lives
the boy is good
what's up
great thinking

it should now be like this
he lives
the boy is good
what's up
great thinking

Last used cell?
Press Ctrl+End to move to what Excel thinks is the last used cell.
Not sure why that would be, unless you have some empty lines at the end of your input file. You can try changing this line:

Code:
If InStr(1, MyResult, vbCrLf & MyLines(i) & vbCrLf, vbTextCompare) = 0 Then
to
Code:
If InStr(1, MyResult, vbCrLf & MyLines(i) & vbCrLf, vbTextCompare) = 0 And MyLines(i) <> "" Then
If that doesn't work, let me know.

it worked partially.
Actually, the empty line used to be three lines there. The code I used to write the text file do add an empty line, while yours do add two, making three altogether.
So this code you gave me
Code:
If InStr(1, MyResult, vbCrLf & MyLines(i) & vbCrLf, vbTextCompare) = 0 And MyLines(i) <> "" Then
reduced the lines to two altogether.

Change this line:

Code:
Print [URL="https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1"]#1[/URL] , Mid(MyResult, 2)

to

Code:
Print [URL="https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1"]#1[/URL] , Mid(MyResult, 2, Len(MyResult) - 2)
</pre>

It's a bit tough to debug at a distance without seeing the file, but here's one last idea. Add one line before the Print #1 line, and change that line to:


Code:
MyResult = Replace(Replace(Trim(Replace(Replace(MyResult, " ", "|"), vbCrLf, " ")), " ", vbCrLf), "|", " ")
Print [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL]  , MyResult

I assume you're not using the "|" symbol anywhere in your file. If so, we can find something else.
