Commands:

2rows           Print the contents of first and last row in each sheet
3rows           Print the contents of first, second and last row in each sheet
bench           Same as "show", but doesn't print -- for profiling
biff_count[1]   Print a count of each type of BIFF record in the file
biff_dump[1]    Print a dump (char and hex) of the BIFF records in the file
fonts           hdr + print a dump of all font objects
hdr             Mini-overview of file (no per-sheet information)
hotshot         Do a hotshot profile run e.g. ... -f1 hotshot bench bigfile*.xls
labels          Dump of sheet.col_label_ranges and ...row... for each sheet
name_dump       Dump of each object in book.name_obj_list
names           Print brief information for each NAME record
ov              Overview of file
profile         Like "hotshot", but uses cProfile
show            Print the contents of all rows in each sheet
version[0]      Print versions of xlrd and Python and exit
xfc             Print "XF counts" and cell-type counts -- see code for details
