First, use the xlsread function to read the file into your workspace.

Unless you absolutely must use the find function, and if your ‘temperature’ data are monotonically increasing, I would use the interp1 function instead. It’s easier, and will give more accurate results if a temperature is not exactly one in your table.

But how to acess next cell

Read everything into your MATLAB workspace with xlsread. It should appear as a (Nx2) matrix (as you’ve described it), so using either find, or preferably interp1, with it would be straightforward after that.
