How to Sort JSON Objects by a Specific Property in Python

In the world of data manipulation, JSON (JavaScript Object Notation) has become a standard format for data interchange. However, sorting complex JSON objects, especially when dealing with nested structures, can be challenging. One common scenario developers encounter is needing to sort these JSON objects based on specific properties.

In this guide, we will take a look at a practical instance: sorting a JSON object by the count property within a nested structure.

The Problem: Sorting a Complex JSON Object

Let's start with a JSON object that contains various resources. Each resource has details and a work attribute with a count. The goal is to sort the entire dataset so that resources are arranged by their count value in ascending order.

Here’s a sample complex JSON structure:

The Challenge

The challenge arises because we want to sort this structure based on the count value found in the nested work object. For those resources where work might be null, we need to handle those cases properly during sorting.

The Solution: Sorting the JSON Object with Python

Step 1: Prepare the Data for Sorting

First, we need to set up the data in a format we can work with in Python. Here’s how we can define the initial JSON data:

Step 2: Sort by the count Property

We can use Python’s built-in sorted() function along with a lambda function to sort our resources by count. Here's how:

This line sorts the resources, placing any resource with work as None at the end of the list.

Step 3: Sort the details by value

If we want to further sort the details for each resource, we can loop through them and apply another sorting operation:

Step 4: Printing the JSON Data

Lastly, we can print the sorted data in a pretty format using Python's json module to see the results:

Final JSON Output

The printed JSON structure should now reflect both the sorted resources and sorted details:

Conclusion

Sorting complex JSON objects by specific properties like count may seem daunting at first, but with Python’s powerful sorting capabilities, it becomes a straightforward task. By using lambda functions and handling nested objects carefully, you can manipulate JSON structures effectively for your data processing needs.
