Excel 2021 can't save a large file from Excel 2010, saying a cell(s) exceeds 8192 characters. (Typically occurs after saving three times.) Excel 2010 (windows 10) has no problem using and saving this file. There's been no problem saving another smaller file from Excel 2010. Have tried search for excessive characters, with no success. Program recommends trying to save in binary mode, which does not work. DG
