How to Convert CSV to JSON with Styles as Lists

Converting data formats is a common task for any data analyst or developer, especially when working with Python. One common need is to convert CSV files into JSON format. However, what if the data in the CSV includes special formatting, such as having multiple entries separated by a vertical bar (|)?

In this guide, we will explore how to convert a CSV into JSON format, specifically ensuring that entries in the "style" field are represented as lists in the resulting JSON.

The Problem

Consider the following CSV content:

When we convert this CSV data to JSON using a simple Python script, the output appears flat, and the styles remain strings separated by |. Here is how the initial conversion looks:

The resulting output will look like this:

This output is not ideal because we require the "style" field to be represented as a list, as shown below:

The Solution

Step 1: Read the CSV File

First, we will read the CSV file and use the csv.DictReader to parse it. This allows us to convert rows of CSV into dictionaries.

Step 2: Replace the Delimiter and Form Lists

For each row, we need to replace the | character with a , and wrap the resulting string in a list format.

Step 3: Serialize to JSON

Finally, we convert the updated dictionaries back into JSON format.

Here is the corrected Python code that implements these steps:

This output meets our requirements, with the "style" field now represented as a proper list of strings.

Conclusion

By performing a few modifications in your Python code, you can efficiently convert CSV data to JSON while ensuring that specific fields are formatted correctly. This method is not only straightforward but also crucial for any data handling where list representation is required.
