Converting YAML Structured Data to JSON in Python

If you are working with YAML files, you might encounter a scenario where you need to convert the data into JSON format for further use or easier integration with other applications. In this guide, we will guide you through the process of transforming a YAML file structured with key/value pairs into JSON, paying special attention to handle nested key/values effectively.

Understanding the Problem

Consider this example of a YAML file:

In this example, we have:

A name field.

A personalInfo section with some nested key/value pairs.

A more section with additional nested keys.

An extra section that has nested keys without associated values.

Your goal is to convert this YAML structure into a correctly formatted JSON output like this:
