How to convert MPDataDoc<PiezoelectricDoc> into a data frame?

Hey everyone, I’m trying to get a dictionary of piezoelectric properties for some materials ids, but instead of a dictionary (as usually) I’m getting a MPDataDoc list (it’s shown on the attached screenshot). How do I convert it to a dictionary and then to a dataframe? Thank you!
