I'm moving away from Microsoft Excel to Open Office but file upload supports ".xlsx". Open Office can generate an ".xls" (older version Excel) and ".ods" (Open Office native format.) As a workaround, I have to embed it in a ".zip" file: Q1_2015_2016_sales.ods - 48 KB Q1_2015_2016.zip - 46 KB The native format ".ods" is ~2% larger so zip is not making a significant space savings. There are file formats that zip actually increases the size. Sure my request helps me but it also frees PriusChat from being perhaps a little too exclusive to recent versions of MicroSoft Excel. Supporting more than one spreadsheet, file type, is a way to help moderate MicroSoft pricing. Bob Wilson
