Is your feature request related to a problem? Please describe.
All raw values of the imported dataset ​​are assumed to be treated as data to be converted from a flat data type like string type

so we need to consider map or list now.

Describe the solution you'd like
We need to make changes to ensure that all the data we maintain has their data type

Describe alternatives you've considered
