How to write a char variable as filename in xlswrite

I am attempting to use an input statement in a loop to prompt me to input the "Patient, Session, Trial" as a char, where it will then use that string to name the .xlsx file. For example, the PST input would be 'P1S1T1', so I want the output of the xlswrite to be 'P1S1T1.xlsx'. Is this possible within xlswrite? Or is there a better way to do this?

This is what I have been tinkering with, I am just unsure how to use the PST variable.

Thanks a bunch

PST = input('Patient, Session, EMG#: ','s'); %saves variable 'PST' as char
xlswrite([PST],'.xlsx',data,1,'A1')

xlswrite([PST],'.xlsx',data,1,'A1')

Passes '.xlsx' as the second input argument to xlswrite. You want to concatenate it with PST instead:

xlswrite([PST,'.xlsx'],data,1,'A1');

Further, you probably want some input validation before calling xlswrite. What if the user types invalid filename characters or nothing at all?

I was close! Just a bracket in the wrong spot, thank you very much. I'll also keep the validation step in mind for executing the code.

Thanks again!
