This file has 528 lines, every line is a repetition of 13 lines, And the 13 lines is a code per a Team link.
I have used and searched many Regex
But only these two was a bit close to what I needed,
Find: ^(.{8}\n)([\S\s] ?\1) and this too ^(.*)([\S\s] ?\1)
Replace All: $2

But I have to push Replace all repetitively, (47 times at least) to reach my goal...

My Desired Output should be out of complete file..

I recommend to use standard functions of Notepad (my version 8.1.9 64 bit) if possible for your needs.

• First open the sample data file (*.txt) by Notepad
• From the main menu go to Edit > Line Operations > Remove Duplicate Lines
• Go to Edit > Line Operations > Sort Lines Lexicographically Ascending
• Format the result as desired for your needs.
