.xls

application/vnd.ms-excel

.xlsx

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

.ppt

application/vnd.ms-powerpoint

.pptx

application/vnd.openxmlformats-officedocument.presentationml.presentation

And one of those you have listed is wrong:

.docx

application/vnd.openxmlformats-officedocument.wordprocessingml.document
