I have a requirement to read .xlsx file in a PL/I program. I was successful in getting the .xlsx but when I try to read the content it is in unreadable form. Could anybody help me to convert the file into readable form. I don't have any knowledge in assembler but I would be happy if I get any help even as an assembler code.
The file encoding is in UTF-8 format, type - text/plain and as an dime attachment.
