Note from the help:

    For performance, import excel imposes a size limit of 50 MB for Excel 2007/2010 (.xlsx) files.  Be warned that importing
    large .xlsx files can severely affect your machine's performance.

Technical note:  Excel data size limits

    For an Excel .xls-type workbook, the worksheet size limits are 65,536 rows by 256 columns.  The string size limit is 255
    characters.

    For an Excel .xlsx-type workbook, the worksheet size limits are 1,048,576 rows by 16,384 columns.  The string size limit
    is 32,767 characters.


This suggests you might be able to read in a larger file if it was in .xls format, but catch-22, xls files can only have 256 columns.
