Is there a way, ideally using the command line, to convert multiple .csv files to one multi-sheet .xls spreadsheet?
If there isn't a cli solution, it'd be good to know if there's an API that works in, ideally, AWK or Pascal, but, failing that, in pretty-well anything.
.xlsfile you could simply do:cat *.csv > file.xls– Ash Feb 17 '16 at 12:05
