We have an Excel xlsx file that opens fine in Office 2007 but when we open using Office 2010 x64 on Windows 7 Enterprise the worksheets are all blank. All the sheets are there with their original names, but the cells contain no data. I converted the extension to .zip and looked at the raw xml and the data is there. If I save the file in 2010, then it saves it blank. We then tried using 2007 to save the file in 97-2003 xls format. That file opens fine in Excel 2010.
Has anyone had a similar issue?
