Finding area of a loop and under a curve

Hello people!

I am analyzing hysteresis of my samples (I am a chemical engineer) and the data is generated in raw form in excel.

Right now I use origin to find the area of loop and are under the upper (or loading) curve to find the hysteresis percentage and then copy it back to excel.

Is there a way to do it in excel itself?

Please refer to the attachment.

Kind regards
