So I have an excel table that I am converting to a tab delimited txt file. The only problem is that at the end of the converted file, there is a blank line. How can i get this to go away automatically?
回答1:
To remove the last empty lines you may use \R+\z regex and replace with nothing.
To remove the last blank line you may use \R\h*\z regex and replace with nothing.
Note that in general you may use
Edit -> Line Operations -> Remove Empty Lines
to remove all empty lines anywhere inside the file.
NOTES on regex:
\R- matches a linebreak (CRLF, or CR, or LF)\R+- one or more linebreaks\h*- zero or more (*) horizontal whitespaces\z- the very end of the file
