Have you tried to search the internet for a simple solution to your problem but not found a suitable one and so started exploring and designing the solution yourself. Yeah! Few times! That’s what I did when I couldn’t find a perfect solution to convert CSV rows to multiple JSON files.
This article classifies as a short course on how to convert CSV to separate JSON files using Python & pandas

I found many sites and blogs with code to convert CSV to JSON files using Python or Perl but they converted entire CSV to a combined JSON file.
All of them were simple and worked well except that all had the basic requirement missing. My requirement was to convert CSV to multiple JSON files to be added to Mongo DB as part of the larger project I am working on. Since I couldn’t find any solution, I decided to make my own 2-step code in python.
Steps to convert CSV to multiple JSON files using Python:
Following are the detailed steps and code written in Jupyter notebook to take CSV as an input and output a separate JSON for each CSV row i.e. effectively convert each CSV row to different JSON file.
- Open the CSV file to convert it’s row to individual JSON files and read the contents in a variable using DictReader() function — this function returns an OrderedDict.

2. Now, to convert this file’s CSV rows to multiple JSON files, we use json.dumps(). So, every row in CSV presented by this OrderedDict, a separate JSON file using json.dumps() will be created. In a way, this implementation of json.dumps() outputs separate JSON for each row in CSV file you provide as input

3. Close the streams.

This will create individual JSON files equal to the number of rows in CSV. So our convert CSV to multiple JSON files mission is accomplished here 🙂
Hope this helped.

What is a CSV file
A CSV is a comma-separated values file having data in a tabular format. Every row has data delimited by a comma. For example, if you copy the following data to notepad and save as tryme.csv, you will be able to open it in Microsoft Excel and see or yourself.
Name, City, Age
Justin, Singapore, 40
Anthony, New York, 38
Mary, London, 29
What is a JSON file?
JSON is an abbreviation for JavaScript Object Notation. It is a novel file format to store information in an organized, computer-readable and workable manner. For instance, the first row of the CSV defined above will be written in JSON as follows:
{
“Name” : “Justin”,
“City” : “Singapore, MT”,
“Age” : “40”
};
