Hi, I have a IF with a not equal for my xlsx file, right now im using a empty string and works perfect, but I want to change that empty string to something like "*xlsx".

You should have used isempty in your current code:
if ~isempty(app.filename)
For the test you now want to do, you should extract the extension with the fileparts function and use strcmp:
[~,~,ext]=fileparts(app.filename);
if strcmp(ext,'.xlsx')
