I\'m completely new to Google Script so bear with me. I\'m attempting to write a script that will take data from several rows and columns and then rewrite it into a single colum
You don't need script. Just put this formula in a cell:
=transpose(split(join(" ",A1:A3)," "))
You can join multiple rows and columns. I tested this on data like you provided in column A & B rows 1 to 3. Works fine.
=transpose(split(join(" ",A1:A3,B1:B3)," "))
