Mastering JSON: How to Recursively Trim Strings in Python

When working with JSON data in Python, you may often encounter strings that have unnecessary extra spaces. These spaces can cause problems in data manipulation and processing. In this post, we will explore how to recursively traverse a JSON object in Python and trim those pesky extra spaces, ensuring our data structure is clean and ready for use.

Understanding the Problem

Imagine you have the following JSON object:

As you can see, certain strings have trailing spaces which may lead to inconsistent data representation. The goal is to create a new JSON object that looks like this:

By the end of this guide, you will know how to efficiently trim these strings from your JSON objects using Python.

Step-by-Step Solution

1. Initial Implementation

You started off with a function that prints each key-value pair, trimming the whitespace. Here’s the initial code:

In this approach, you’re able to iterate through the JSON structure and print each key alongside its trimmed value. However, this does not yield a new JSON structure; it simply outputs the trimmed strings.

2. Updating the Values in Place

To achieve the desired outcome, we will need to update the JSON object in place instead of just printing the values.

Here’s the modified function:

3. Putting It All Together

Now, let’s see how to apply this function to our initial JSON data:
