How to detect which type of data user selected 'text' or 'excel' file via "uigetfile" and then perform further code?

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.

Dear Cris Thanks for ur Guidence and Support, i have viewed in detail >> [file,path,indx] = uigetfile and "fileparts" and trying to find the desired result.. You answered correctly but i think i failed to explain my querry Correctly... if i resummarise my desire again, i want the following code to work.. means if user selected "text" file relavent code will run, if user selected excel file the second code will run... it will be a great favour if u correct my code or Reshare it.. Attached Code file and data files..

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
