How to Convert Json Type to Dataframe In Pandas?

10 minutes read

To convert a JSON object or file to a DataFrame in Pandas, you can use the pd.read_json() method. This function will read the JSON data and convert it into a DataFrame format. You can pass the JSON object directly as a parameter or provide the path to the JSON file. The JSON object should be in a valid JSON format for it to be successfully converted to a DataFrame. After converting the JSON to a DataFrame, you can manipulate and analyze the data using Pandas' functionalities.

What is the utility of .loc and .iloc in pandas?

The .loc and .iloc methods in pandas are used for indexing and selecting data from a DataFrame.

  • .loc is label-based indexing, where you can specify rows and columns by their indexes or labels. You can also use boolean masks to filter data.
  • .iloc is integer-based indexing, where you can specify rows and columns by their integer positions.


These methods are useful for selecting specific rows and columns from a DataFrame, and for slicing and filtering data based on certain conditions. They provide a flexible way to access and manipulate data in a pandas DataFrame.


What is the purpose of JSON parsing in pandas?

The purpose of JSON parsing in pandas is to read and convert JSON (JavaScript Object Notation) data into a pandas DataFrame, which is a two-dimensional tabular data structure. This allows for easier manipulation and analysis of the data within the pandas framework. JSON parsing in pandas is particularly useful for working with JSON data obtained from web APIs, databases, or other sources.


How to select specific columns in a pandas dataframe?

To select specific columns in a pandas dataframe, you can use the square bracket notation and pass a list of the column names you want to select. Here is an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
import pandas as pd

# Creating a sample dataframe
data = {'A': [1, 2, 3, 4],
        'B': [5, 6, 7, 8],
        'C': [9, 10, 11, 12]}

df = pd.DataFrame(data)

# Selecting specific columns 'A' and 'C'
selected_columns = df[['A', 'C']]

print(selected_columns)


This will output:

1
2
3
4
5
   A   C
0  1   9
1  2  10
2  3  11
3  4  12


In this example, we selected columns 'A' and 'C' from the dataframe df and stored them in a new dataframe selected_columns.
