There's not a lot to go on, but my only guess is you don't have MS Office Excel installed on a Windows machine. Without Excel installed, xlsread operates in 'basic' mode, which does not support the numeric worksheet input. Considering no sheet number input defaults to the first worksheet, simply try:
xlsread(fileread);

Can you elaborate when the error occurs and on which files?
Also xlsread will not work if the file is opened in Excel.

"Also xlsread will not work if the file is opened in Excel."
I just tested that explicitly this morning and it does in fact work. At least with whatever edition of Excel I have (2013? maybe), and R2017b on Win10.
I also checked having a file with no worksheets, but Excel won't let you do that. Maybe if some other application created a .xls file with no sheets...
