Transform GA API Output to Structured JSON Format Using Jolt

When working with data retrieved from Google Analytics (GA), it’s common to encounter outputs in various formats. One common challenge faced by developers is transforming these outputs into a structured JSON format that is more suitable for storage or further analysis. This guide will guide you through the process of converting GA API output into a structured JSON format using Jolt Transformation.

The Problem Overview

Upon querying data from the Google Analytics API, you might receive the following unstructured format:

This format is not readily useful for database storage due to its nested structure. Your goal is to transform this output so that it can be easily understood and utilized within databases.

The Required Output Format

You want to restructure the output into a more coherent and organized JSON format like the following:

This new format ensures that each row of data is represented as a structured object.

The Solution: Using Jolt Transformation

To achieve the required output, we can use a tool called Jolt, which specializes in transforming JSON data. Below is the step-by-step approach to create a Jolt specification for this transformation.

Jolt Specification

Here is the Jolt specification that will help you transform the JSON data into the desired format:

Explanation of the Jolt Spec

Operation: The "operation": "shift" command dictates how to change the input structure.

Spec Section: This section maps the input fields to the desired output structure by indicating where each data point should go. The indices inside the rows array directly correspond to the indices from the original input format.

Applying Jolt Transformation

Input: Use the original GA API output as input for the Jolt transformation.

Execution: Run the Jolt transformation using your favorite programming language that supports Jolt or an online tool that provides Jolt transformation capabilities.

Output: Upon successful application of the Jolt spec, you will receive your data in the structured JSON format.

Conclusion

Transforming Google Analytics API output into a structured JSON format can streamline data storage and analysis. Using Jolt for this transformation provides a flexible and efficient way to handle JSON data restructuring. By following the steps outlined above, you can ensure that your data is in the right format for your database or analytic needs.

By mastering these transformations, you can significantly enhance your data processing workflow and make more informed decisions based on properly structured analytics data.
