I need to fill values across a distance of 10,000 (yes, 10k) columns, BUT only every ten columns. So the spreadsheet will be 10,000 columns wide, and the cell values in row 1 will be column 0 = 0, column 10 = 10, column 20 = 20 and so forth. The intervening cells will be blank. Is there anyway to easily do this? The blank cells are the difficulty and my Google-fu has failed to come up with an answer. The following rows will be similar but with different (larger) numbers.
