DictReader ( csvfile, fieldnames ) for row in reader : json. The below example code demonstrates how to convert a CSV file to a JSON file in Python using the Dataframe.to_json() method.Import csv import json csvfile = open ( 'file.csv', 'r' ) jsonfile = open ( 'file.json', 'w' ) fieldnames = ( 'FirstName', 'LastName', 'IDNumber', 'Message' ) reader = csv. Since the Dataframe.to_json() method takes a DataFrame as input, we will use the pandas.readcsv() method to first read the CSV file as DataFrame. The orient argument is useful to specify how we want our JSON string to be formatted, and there are various options for both Series and DataFrame input. If no path is provided, the method returns the JSON string as output and returns nothing if the path is provided.

The Dataframe.to_json(path, orient) method of the Pandas module, takes DataFrame and path as input and converts it into a JSON string, and saves it at the provided path. With open( 'myfile.json', 'w') as file_json:Ĭonvert CSV File to JSON File in Python Using the Dataframe.to_json() Method in Python The below example code demonstrates how to use the json.dump() method to save the data as JSON file in Python. The separator argument is equal to (', ', ': ') if indent argument is None otherwise, it is equal to (',', ': '). For indent argument value equal to 0, the method adds a newline after each value and adds indent number of at the start of each line.

The indent keyword argument can be used if we want to add the indentation to the data to make it easier to read. The json.dump(obj, fp, indent=None, Seperator=None) method takes data obj as input and serializes obj as the JSON formatted stream, and writes it to the file-like object fp.

We can convert the CSV file to a JSON file in Python by using the following methods. So, we need some method to convert the CSV format data to JSON format. Suppose we have data saved in CSV ( Comma Separated Values) format, and we need to convert it to JSON format. In web applications, the format used to save and transfer data is the JSON format. This tutorial will demonstrate various methods to read data from a CSV file and save it as a JSON file in Python.
