How to Convert a Text File to JSON Format in Python: A Step-by-Step Guide

Are you looking to convert a list of strings from a text file into a well-structured JSON format? If so, you’re in the right place! In this post, we'll walk you through the common problem of transforming text data into JSON using Python, complete with a straightforward solution and code examples.

The Problem

You have a file, sample.txt, containing a list of numbers like so:

The goal is to convert this data into a JSON format that looks like this:

The challenge arises when your initial code only reads every other line of the text file, leading to incomplete JSON output. Let’s explore how to resolve this issue.

The Solution

To achieve the desired output, you can simply read each line of the text file without using the zip function. This straightforward approach allows you to gather all the necessary data. Below, you will find the revised code that correctly processes the entire file.

Step-by-Step Code Implementation

Import necessary modules: We will only need the json module.

Read from the text file: Open the sample.txt file and iterate through each line.

Process each line: For each non-empty line, create a dictionary with your specified structure.

Write to a new JSON file: Finally, save the output formatting as JSON in a new file.

Here’s the complete code:

Code Explanation

Reading Lines: The for line in f_in loop reads through each line of the text file. The strip() function is utilized to eliminate any surrounding whitespace, ensuring that we only process relevant data.

Skipping Empty Lines: The line if not line: continue ensures any blank lines in your input file do not produce empty JSON objects.

Formatting the Output: The result.append(...) line adds a new dictionary to our list for each non-empty line.

Output to JSON: The json.dumps(result, indent=2) method formats the output for readability, and we write it to formated.json.

Conclusion

By following the code example provided, you can effectively convert any list of strings in a text file into the desired JSON format. This knowledge will prove invaluable when handling data transformation tasks in your Python projects. Whether you’re a seasoned developer or a beginner, mastering this skill is a step toward producing cleaner, more structured data representations.
