All works well with openoffice. There is no issue with xls or xlsx files. But field do not take with MS WORD files.
I cannot get docx file to import patient data. I cannot get doc files to work either.
Very limited success with Word Template files dotx if they are saved as Word 97-2003 compatible. The templates I have in Word uses drop down menus and calender pick any date fields from" Word developer tap". It would be a lot of work to convert all the files to odt.
I think xmlformgen is much more difficult to use than LBV forms for those of us who are not programmers. Also more documentation on the latter.
LBV forms can be created with Data Type, Text-date, which renders a pop-up calendar in the body of the form.
See attachment.

If you have only OpenOffice installed on your device, there is a popup asking if you wish to save a Word document as .odt. The conversion is done automatically without another application.
