You may use interpolation (the simplest is linear interpolation, more elaborate the three flavors of cubic splines) or you may use approximation (Mathcad offers a number of different fit functions and also a generic "genfit"). If you do not want to use the built-in fitting functions you may also use a solveblock with minerr.

You can insert an Excel component in your sheet, but personally I find it more convenient and straightforeward to use the READEXCEL function.

BTW, as far as i know all built-in curve fit function would just deal with 2D data. For 3D data you would have to resort to a solve block as already mentioned, I guess.
