I have xml files created with ODS tagsets.excelxp and would like to
convert them from plain xml to xls and/or xlsx. I can open them in
Excel and Save as..., but need to do it automatically from a SAS
program. The sheets in the files are not just one rectangular data set
each, but two or more data sets with different columns. Also the
sheets contain a lot of formatting. So just importing the xml and
exporting to xls/xlsx wouldn't work, I guess.
