Hi Kevin
I would use 'Data - Text to columns'. Choose fixed lenght though this
will be quite an effort to choose the delimiting positions for 512
characters :-).
You can also enter the following array formula:
=MID(A1,ROW(INDIRECT("1:" & LEN(A1))),1)
select the target rows, enter this formula and hit CTRL+SHIFT+ENTER
(assumption: A1 stores your string)

Hello,

How would I convert a single cell string consiting of 512 values:
545, 565, 576, etc... to a range of 512 cells.

Thanks, Kevin Graham
