Linking JSON Data on Key IDs: A Step-by-Step Guide to Creating a New JSON File

In today's data-driven world, working with structured data formats like JSON is a common task for developers and data analysts alike. One specific use case involves merging two JSON arrays based on a key identifier—allowing us to create a more efficient data structure. This guide will walk you through the steps needed to link a JSON file containing stations and prices into a new, unified format.

The Challenge: Merging JSON Data

You may find yourself in a situation where you have a JSON structure similar to the one below:

The goal is to transform this data into a new JSON format that consolidates all information under the respective station codes, producing something like this:

The Solution: Using PowerShell to Transform JSON

To achieve this transformation without overloading the client-side performance, we can use a scripting language like PowerShell. Follow these steps to create your new JSON file:

Step 1: Define Your JSON Data

Start by defining your initial JSON data:

Step 2: Iterating Through the Prices

Next, you'll need to iterate through the prices and merge them with the corresponding stations:

Conclusion

By following the outlined steps, you can efficiently link your JSON data based on key IDs and transform it into a more usable format for your applications. Utilizing PowerShell not only automates the data structure modification process but also saves you from potential performance hits on the client side.

If you want to improve your data handling capabilities further or explore other programming languages (such as Python or Dart), the principles remain largely the same. Happy coding!
