I got an Excel file, actually it's a zip file which contains many folders and files including sheets in XML format. When I try to open it, Excel 2003 says "The file is not in a recognizable format"
I've uploaded to Google Documents, Google recognized the format then I've saved as Excel 2003.
I've already installed Microsoft Office Compatibility Pack.
I renamed .xls to .zip then unzipped the content. Below are the unzipped folder content:
xl Content_Types.xml docProps _rels
How can I open that Excel File?
