Using xlsread with multiple delimiters

Hi,
I want to write a script, which can import xlsx, txt and csv files. Therefore I use xlsread. I know it's not recommded, but I have no headers, so readtable is no option. But I struggle to add multiple delimiters into the code of xlsread. I tried this code:
directory_name=uigetdir('','Waehl den Ordner mit den Messungen');
[nur_file_name,pfad]=uigetfile({'*.csv;*.txt;*.xlsx','csv&xlsx&txt-files (*.csv,*.txt,*xlsx)';'*.*','all Files'},...
'Die Intensitäts-Files der Proben oeffnen (probe_001.txt=',...
[directory_name '/'], 'Multiselect', 'on');
[num,txt,raw] = xlsread(filename{xy}, [',' ';' '\t'], 'B1:KR1');
But it is sadly not working in the last line. The delimiters are not accepted in this form. I am grateful for every hint.

Tatjana Mü's incorrectly posted "Answer" moved here:
I realised I did a huge mistake. xlsread is really the wrong option - I am sorry. So most important is to read in the file "SMP_Std.csv". Most of my files will be like this.
The probleme is the seperation with a ','.
I just added a picture, how excel is opening the file. Everything is in one cell.
So I want to read in this file.
[num,txt,raw] = xlsread(filename{xy}, 'B1:KR1');
element_cim=string(txt);
element_cim(:,[5 7:29 31:32)=[];
element_cim=regexprep(element_cim,'\[','');
element_cim=regexprep(element_cim,'\]','');
element_cim=regexprep(element_cim,'\''','');
element_cim = convertStringsToChars(element_cim);
element_cim=char(element_cim);
end
xlsread is not working. I want to read in the range from 'B1:KR1'. Then I delete some columns, delete some columns and parts of the element name and want to receive a char like this:
val =
'23Na+ '
'24Mg+ '
'25Mg+ '
'26Mg+ '
'27Al+ '
'39K+ '
'40Ca+ '
'41K+ '
'42Ca+ '
'43Ca+ '
'87Sr++ '
'88Sr++ '
'44Ca+ '
'45Sc+ '
'46Ca+ '
'48Ca+ '
'50Cr+ '
'50V+ '
'51V+ '
'52Cr+ '
'53Cr+ '
Do you know how I receive this?

"The probleme is the seperation with a ','.... I just added a picture, how excel is opening the file. Everything is in one cell."
Sure. Those a problems that Excel has due to your OS's delimiter settings (i.e. locale settings).
But that has nothing to do with MATLAB.

Ran in:
Without a sample XLSX file I had to create my own (attached).
It is easy to read the first line using READCELL, it will correctly indentify the delimiter character:
firstrow('SMP_3.8.1.csv')

No, do not change the function like that (it is invalid sytnax to put any indexing into the function signature line).
I doubt that you need to change the function much, most likely you can just call it like this:
[fnm,pfad] = uigetfile(.. whatever you want here..);
out = firstrow(fullfile(pfad,fnm))
If you do not use FULLFILE then you will have problems with the file not being found.
