Solving JSON Encoding Errors in Python: A Step-by-Step Guide

When working with JSON files in Python, you might encounter frustrating encoding issues. Particularly, a common problem surfaces when reading a JSON file that leads to strange characters appearing between every letter. This typically indicates an encoding mismatch, which can stop your code in its tracks. In this post, we will explore a solution to this problem step-by-step.

The Problem: Strange Characters in JSON

Imagine you're trying to load a JSON file. After reading the file, instead of obtaining the expected data, you’re met with a string filled with unrecognizable unicode blocks between every character. Here's an overview of the most critical symptoms and the error message that follows:

Unexpected Output: Instead of parsing your JSON correctly, you see something like this:

This issue can be quite irritating, especially for newcomers in programming or data manipulation in Python. Fortunately, the resolution is usually straightforward once you understand the core problem: encoding.

The Solution: Correctly Specifying Encoding

The root cause of this issue often lies in the encoding of the JSON file you are trying to load. In many cases, the file may be saved in UTF-16 format, while your code is assuming it is in a different encoding, such as ASCII. Here’s how to fix it:

Step-by-Step Guide

Identify the Encoding Type:

The first step is to determine the encoding of your JSON file. In this example, we discovered that the encoding was UTF-16 LE (Little Endian).

Modify Your Code:

Update your code to specify the correct encoding in the open() function. Here’s an example of what your modified code should look like:

Verify Output:

After applying this change, running your modified code should yield a properly structured JSON output, like so:

Conclusion

By simply specifying the correct encoding when opening your JSON file, you can avoid frustrating decoding errors. The key takeaway here is to always verify the encoding of your files, particularly when working with external data sources. This small adjustment can save you a lot of time and headaches in your programming journey.
