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.
