Making a humanoid avatar animation smoother given a CSV file of joint position data ,Making human avatar animation smoother with given joint position data in CSV file

I am working on a project where I need to render a human avatar with a given CSV file or data steam that contains the real-time joint position data of a human subject. I had a very basic rendering going on but the animation is very jittering and it doesn’t stay on a horizontal level (since the joint position data of feet changes from frame to frame and the model’s root joint is hip). I am wondering if there is any way to make the animation smoother and make the human avatar plants it’s feet on the ground. I assume that I have to transform the input data like normalizing it somehow to accomplish this goal, but I don’t know a good way to proceed.

Any help is appreciated!,I am working on a project where I need to render a human avatar with a given CSV file or data steam that contains the real-time joint position data of a human subject.
