Converting a Text File to JSON using Python: A Step-by-Step Guide

In the world of data processing, transforming data formats is a common task that developers encounter frequently. One such transformation is converting a plain text file into JSON format. This article will walk you through the method of converting a text file containing key-value pairs into a structured JSON file using Python.

Understanding the Problem

A text file might contain data in a simple format, such as key-value pairs separated by colons (:). For example:

Step 3: Split and Append

For each line, use strip() to remove any leading/trailing whitespace.

Use the split(':') method to separate the kid and hex_key values.

Store each pair in a dictionary and append it to a list.

Step 4: Convert to JSON Format

Finally, use json.dumps() to convert the list of dictionaries into a JSON-formatted string.
