When importing a spreadsheet, importdata returns a scalar structure array (see here). Your error, then, is because you are not accessing the data properly (see examples on the page I linked to).
Is there a reason you are using this import function? I'd suggest using readtable instead. You will have to learn how to access data in a table as well. I'd suggest this short video.

Answer:
X= X.data(:,1);
TempK = ((X1-32)*5/9)+273.15;
