Still it's not getting split into columns.

referred this stackoverflow solution: df = pd.DataFrame({'id':[1,2,3], 'col1':[{'a':1, 'b':2, 'c':3}, {'a':3, 'b':4, 'c':5}, {'a':None, 'b':5, 'c':6}]}) df.set_index('id').col1.apply(pd.Series) working for this data frame, but not working for my original one.

Try using json normalise:

import pandas as pd
df2 = pd.json_normalize(df['address'])
