Converting Your Text File to a Nested JSON in Python

In the world of data transformation, one common challenge developers face is converting a flat text file into a more structured format, such as JSON. This task is particularly important when you want to analyze, visualize, or manipulate the data contained within a text file. In this guide, we will explore how to convert a flat text file into a nested JSON structure using Python.

The Problem

Imagine you have a text file structured like this:

Your goal is to convert this text into a nested JSON format, which looks like this:

The challenge arises in defining the structure of the resulting JSON, particularly the nesting required for attributes that depend on certain keys.

Steps to Solve the Problem

To achieve the desired nested JSON structure, follow these steps:

1. Define Your Nesting Structure

Before diving into the code, we need to determine how the keys and values should be nested. For instance, under each Job_ID, there will be a series of Stage_ID entries. Thus, we can define our nesting structure in Python as follows:

2. Initialize Result Variables

We will need to initialize a few variables to hold our results and manage our collections:

3. Process the Input String

Next, read the input text string and iterate through each line to populate our result_dict.

Here’s a simplified version of the code that accomplishes this task:

4. Handling Nested Structures

While processing the lines, the code should dynamically adapt the dictionary structure based on the current key being processed. This involves checking if the current key indicates a new section (like Job_ID) or if it belongs to an existing one. If it's a new section, the nesting needs to be reset.

5. Output the Result

After processing all lines, you can convert the result_dict to JSON format using the json library:

Example Output

When the above code is executed, it generates a nested JSON structure that elegantly represents the relationships specified in your text file:

Conclusion

Converting a flat text file to a nested JSON structure in Python requires you to define the nesting rules programmatically. By following the structured approach we discussed, you can transform your data into a usable JSON format efficiently.
