You can achieve this by using the map function to convert each inner array into a list. Here is an example: import pandas as pd import numpy as np # assuming companyY is your data structure pd.DataFrame(map(list, companyY)) Alternatively, you can use the unpacking operator (*) to achieve the same result: pd.DataFrame([*companyY]) Both of these methods will convert each inner array into a list, and then create a DataFrame from those lists.
