I've got a large file with several sheets of 40,000 lines and half a dozen columns. To try and reduce the size of the file I have cleared all unoccupied cells and saved as much as possible as values. I can't store the data as a pivot table.
Another thing which seems to be helping is replacing where possible whole words with codes, so instead of Afghanistan, Albania etc I am saying 1, 2 etc, and pulling back the real name later on. This is apparently having some effect, but not as much as I was hoping. Does one character in a cell occupy 1 Byte of memory? And if so, does a column of 20k single characters occupy 20k of memory? And if so, does the number 123 occupy 3 Bytes? and if so, could I reduce it to a single Byte by coding it as capital H, say?
Thanks to anyone who can advise me on this or on other ways of reducing file size. I have had a quick look at the search results for this, so apologies if I'm suggesting something already well known.
