Create Panels from Radiation grid

Dear All,
I am wondering if it’s possible to convert each grid to a panel. I have set a 1.2m grid and I want my panels to have the same size.
Basically, if I have this grid:

I want something like this:

Later, I will then map the values of each grid to be assigned to the Extrusion depth (this step, I will figure out later)… But for now, I need to create panel from the grids themselves.

I tried the mesh but they don’t seem to be following the grid specially on the edges. Also, If they do, I also don’t know how to convert them into 4-edge surfaces.

Thanks,
JM
