Not to complicate too much, I suggest that you save *.xls or *.xlsx file to *.csv (comma separated value file) and then use (read-line) function to read each row of sheet which is separated by "," ";" or "\t" string after which you can sort columns values and create corresponding list of strings of complete sheet excel table...
