    for colx, text in enumerate(row):
      ws.write(rowy+ 1, colx, text)
def main(dbpath):
  xlspath = dbpath[0:dbpath.rfind(&#39;.&#39;)] + &#39;.xls&#39;
  print "<%s> --> <%s>"% (dbpath, xlspath)
  db = sqlite.connect(dbpath)
  cur = db.cursor()
  w = Workbook()
  for tbl_name in [row[0] for row in sqlite_query(cur, &#39;sqlite_master&#39;, &#39;tbl_name&#39;, &#39;type = \&#39;table\&#39;&#39;)]:
    sqlite_to_workbook(cur,tbl_name, w)
  cur.close()
  db.close()
  if tbl_name !=[]: w.save(xlspath)
if name == "main":
  # arg == database path
  main(sys.argv[1])
