How to get nodal values in OpenFOAM?

I would appreciate knowing how I can convert the cell values given after the OpenFOAM solution into the ones on the grid points. Is there any direct command for such a thing or I should work with the sampling option?

Thanks a lot for your help.

    types of fields

    You can also see the values of the fields (points or cell) using the Spreadsheet view and export them as CSV:
