Ok, here is the deal - I copied text from some online table, and in notepad, it spans to multiple lines - each line per column. I wanted to grab only certain lines and soon became too tired to do this manually. So I wrote this calculator below.
Just paste your text with multiple lines, set the start line, and how many lines to remove after the start line. The process is repeated until you have only filtered lines. It works fine for me; I hope it can be useful for someone else too.
