I keep getting an error when trying to run the following command from the MATLAB Fundamentals class (pg 6-11 in course notes). Doesn't writetable overwrite a file if it already exists?

writetable(standings,'EPLstandings.xlsx')

Error using writetable (line 121) Unable to save the workbook to file 'C:\EPLstandings.xlsx'. Check that write permissions are available, there is sufficient disk space, and the file can be written to or created.

I was having the same error. In the section in your matlab window, I selected desktop and it automatically create the folder!

Try the following solution that worked for people with same issue:

After creating the two above-named folders, the MATLAB script's writetable() call now correctly creates the .xlsx file.

 You have to create a folder (or two on a 64bit-windows):
 (32Bit, always)
 C:\Windows\System32\config\systemprofile\Desktop
 (64Bit)
 C:\Windows\SysWOW64\config\systemprofile\Desktop

After creating the two above-named folders, the MATLAB script's writetable() call now correctly creates the .xlsx file.

Thank you Varun! After adding the above-mentioned folders, the writetable call worked successfully.

I recommend you avoid creating or modifying files inside your MATLAB installation. Create another directory, something like c:\mywork, and cd to that directory before saving your files.
