Excessive formatting.
Happens when formatting gets applied to entire rows, entire columns or all cells of a sheet.
In particular the Apple date & ginger and the Apple pear & apricot sheets which have some kind of formatting applied all the way to cell "IV65536" (that's row 65536 column 256) but the last used cells are actually "F22" and "H24".
Need to delete the rows and columns beyond those actually being used.
After running this "Lose That Weight" macro to automatically do this for all sheets in the workbook the saved size was around 33KB.
Code:
Sub LoseThatWeight()
