@by-eck I’m late to this, but I wonder if Notepad++ is the right tool for this job. If you have to do it more than once - a simple automatic text editor like “sed” would be more suitable.
It also resembles work I’ve had to do to copy database data to a format that pastes into Microsoft Excel out of “SQL Server Management Studio”. In that case, I wrote a fairly simple SQL user-defined function, whose output is what I want Excel to receive, starting with changing ‘01’ to =“01” so that Excel displays 01 instead of the number 1 - but also removing in-data line breaks and tabs and anything else that annoyed me. Oh, I think it fixes dates. So the output of the data process didn’t contain those hiccups.
I did that as paid work so I guess my employer owns it, but they may agree to sharing it with the world. Would you like me to ask?
