Thxk for the effective call blocking app! Very nice indeed.

I have over 9 thousands junk numbers that want to be blocked. They all are in separate new line. I see the config file and the blacklist numbers are in the same line separated by comma

black=12345678, 23456789, 34567890,.......

Does anyone know a effective or fast way to turn over thousand of numbers in separate line to the same line separated by comma?
