certainly! in this tutorial, we will learn how to convert a csv file into multiple json files, where each row in the csv will correspond to a separate json file. this can be particularly useful when you want to process or store individual records separately.

step-by-step guide

step 1: set up your environment

make sure you have python installed on your machine. you also need to have the `pandas` library, which simplifies data manipulation. you can install it using pip if you haven't done so already:



step 2: prepare your csv file

create a sample csv file named `data.csv`. here's an example of what it might look like:



step 3: write the python script

now, let's write a python script that reads the csv file and converts each row into a json file.



step 4: run your script

after writing your script, save it as `csv_to_json.py` (or any name you prefer). then, run the script:



step 5: check the output

after running the script, you should see a new directory named `json_output` containing individual json files for each row in the csv. for the provided example, you will have:

`json_output/row_1.json`
`json_output/row_2.json`
`json_output/row_3.json`

each json file will contain the data for that specific row. for example, `row_1.json` will look like this:



explanation of the code

**import libraries**: we import `pandas` for handling the csv and `json` for writing json files. `os` is used to create a directory for the output files.
**create output directory**: we check if a directory named `json_output` exists, and if not, we create it.
**read csv**: we read the csv file into a pandas dataframe.
**iterate rows**: we loop through each row of the dataframe and convert it into a dictionary.
**write to json**: for each row, we create a json file named after the id (or any unique identifier) and write the row's data to that file.
