    book = xlrd.open_workbook(filename)
File "F:\helium2.1\lib\xlrd\__init__.py", line 370, in open_workbook
    biff_version = bk.getbof(XL_WORKBOOK_GLOBALS)
File "F:\helium2.1\lib\xlrd\__init__.py", line 1323, in getbof
    raise XLRDError('Expected BOF record; found 0x%04x' % opcode)
XLRDError: Expected BOF record; found 0x4b50

办法：xlrd只支持‘xls’文件。不支持office2007

If you upgrade to the latest version (0.7.0) of xlrd (go to http://pypi.python.org/pypi/xlrd), you'd get a slightly better error message:Unsupported format, or corrupt file: Expected BOF record; found 'PK\x03\x04\x14\x00\x06\x00'Trivium: 'PK' == initials of Phil Katz, designer of the ZIP file format.Currently, xlrd supports reading only xls files. What you have is probably an xlsm file ("Excel 2007 Macro-Enabled Workbook"). These and xlsx files ("Excel 2007 Workbook") are in a format (XML documents inside a ZIP file) that's totally different to the format of xls files.Support for extracting the basic data (no formatting info) from xlsx and xlsm files is well under way.
