My spreadsheet has 6,000 rows by 14 colums; the 1st column is hyperlinks to
URLs. The file size is 7.5MB with the hyperlinks, but when I save the file
without the hyperlinks (copy column and paste special-values), the file is
only 0.5MB. Is this file size difference OK? The large file has some
unusual behavior (some math errors for averages) and I'm not sure if the file
is corrupt.
