- extList is a cell array of character vectors that contain the user's input list
- nExt is the number of extensions entered
How to ask the user how many file extensions to search for

I currently have a script which find files in a folder with a matching string that the user inputs.
I also have code where the user enters the file extensions he wants the script to look for.
ext1 = inputdlg('Please enter file extension #1: **\*. ');
ext2 = inputdlg('Please enter file extension #2: **\*. ');
ext3 = inputdlg('Please enter file extension #3: **\*. ');
fileData = [dir(fullfile(fileLoc,char(ext1))); dir(fullfile(fileLoc,char(ext2))); dir(fullfile(fileLoc,char(ext3)))];
What I want to do instead of ask the user how many different file extensions he wants to look for and then ask for them accordingly.
(e.g. User inputs he wants to search for 5 different file extensions and the script asks for 5)
I'd like to do this instead of just hard-coding in how many file extensions he can search for.

That's too much work (for you and the user). Instead, the user could just list all file extensions in the first dialog, separated by commas. Then you can separate that list into individual extensions.
ext = inputdlg('Please enter file extensions separated by a comma: **\*. Example: txt, csv, ogg');
if ~isempty(ext) %check if user entered anything
% Separate selections
extList = strtrim(strsplit(ext{1},','));
extList(cellfun(@isempty,extList)) = []; % get rid of empties (if any)
nExt = numel(extList); %number of extensions
end
For example, in the inputdlg enter this: txt, csv, ogg, xlsx
If there is a set list of possible file extensions, a better idea would be to use a listbox where the user can merely select from a set of options.

Hmmm, could you show us exactly what's in ext and the result of class(ext)?
[update]
I just embedded the code from my answer into app designer and entered a variety of inputs including several extensions, 1 extension, and empty, and there was no error.

So somehow ext is a character vector instead of a cell array of char.
As a general fix: after you have called
ext = inputdlg('Please enter file extensions separated by a comma:. Example: txt, csv, ogg: ');
add
ext = cellstr(ext);
Though you might have to check isempty() first.

inputdlg should always return a cell array:
Where is the 'txt, pdf, docx' char array coming from? I can't be the output to inputdlg.

I'm not sure how that solved the error you were getting.
Notice at the end of this line you transpose the array.
fullPaths = strrep(fullPaths,fileLoc,'')'; % Remove the header path
% HERE ^
So when you comment that out, fullPaths remains as a row-cell-array.
That causes the error when you try to horizontally concatenate the bottom line below.
outputData = [{'Starting Path:' fileLoc ' ';
'Time to Execute:' [sprintf('%.2f',overallTime+overallTime2) 's'] ' ';
'File Count:' num2str(sum(finalFlag)) ' ';
'Date' 'Size (kb)' 'File'};
fileDates(finalFlag) num2cell(fileSizes(finalFlag) ./1024) fullPaths(finalFlag)];
%|___column array___| {______________Column array_________| |____Row array______|
