In this article, we will study how to convert JSON to Pandas DataFrame in Python. So, we need to deal with the external json file. Convert String to JSON Object in Python In most web APIs, data which transmitted and received are generally in the form of a string of dictionary. In our case, the album id is found in track['album']['id'], hence the period between album and id in the DataFrame.This makes things slightly annoying if we want to grab a Series from our new DataFrame. Let us now see how to convert json to pandas DataFrame using Python. data = [ [ 'Axel', 32 ], [ 'Alice', 26 ], [ 'Alex', 45 ]] df = pd.DataFrame (data,columns= [ 'Name', 'Age' ]) df.to_json ( 'example.json') Load JSON from File.

Indeed a lot of python API returns as a result of JSON and with pandas it is very easy to exploit this data directly. The text in JSON is done through quoted-string which contains value in key-value mapping within { }. How to add new column to the existing DataFrame, How to play random mp3 from a folder in Python, How to add two numbers represented by linked list in C++, Python Program to Print Trinomial Triangle, Maximum value of XOR among all triplets of an array in Python, fegetenv() and fesetenv() functions in C++, Check if a Key Exists in a JSON String or not in Python.
