Convert OXPS to XLSX

OXPS documents are exclusively exported with the XPS tool pre-installed  Windows 8/10. Your best option for exporting documents (recovery) from .oxps files would be to first convert oxps to xps, which is a little more supported format.

Once this is done and you have the .xps file, you will have to use of the XPS conversion tools to try to export it as Excel spreadsheet (.xls, .xlsx). If you still have trouble with getting the data as spreadsheet, try to first convert xps to pdf before finally converting it to the format you need.
