i have written a code that allows user to input data and give both options of "text" and "Excel"..that is
[filename, pathname] = uigetfile({'*.xlsx','Excel Files(*.xlsx)'; '*.txt','Txt Files(*.txt)'}, 'Pick a file');
if '*.xlsx' % if excel file select
disp('User Selected Excel File.');
else
disp('User Selected Text File.');
end
% i tried isfile function but is detects data type.. kindly Guide. Thanks

Use this syntax of uigetfile
[file,path,indx] = uigetfile
Here, indx corresponds to what filter was selected (see here). If that doesn't work, you can implement your own check using fileparts.
[filepath,name,ext] = fileparts(filename)
Here, ext will be the file extension of filename.

I understand what you are trying to do, but you have not coded it correctly. For example
if '*.xlsx' % if excel file select
does nothing right now because you have not correctly set up the conditional statement.
I suggest going through Ch 13 of MATLAB Onramp, which will introduce you to if statements. Perhaps that will help you see how to use what I shared to obtain what you want.

Dear Thanks More than Thanks for ur Help, which Finally lead me to achieve my goal.. So nice of You.. Sharing the Working Code and code file attached also..
clc; clear all; close all;
BaseDir = 'C:\Program Files\Matlab\bin\';
[filename, pathname] = uigetfile({'*.xlsx','Excel Files(*.xlsx)';...
'*.txt','Txt Files(*.txt)'}, 'Pick a file', BaseDir);
if isequal(filename, 0)
disp('User aborted file choosing.');
return;
else
[fPath, fName, fExt] = fileparts(filename);
switch lower(fExt)
case '.xlsx'
disp = 'User Selected Excell Data'
case '.txt'
disp = 'User Selected Text Data'
otherwise % Under all circumstances SWITCH gets an OTHERWISE!
error('Unexpected file extension: %s', fExt);
end
end
