How to Convert a Text Response into a JSON Array in Postman

When working with APIs, you may often find yourself needing to handle responses in different formats. One common situation is when your API returns a plain text response, and you want to transform it into a more structured format, such as a JSON array. This guide will guide you through the process of converting a text response into a JSON array using Postman, which will make it easier to manage your API requests effectively.

The Problem: Handling Text Responses

Recently, a user faced a challenge while attempting to convert a text response in Postman into a JSON array. Here's a simplified version of what their text response looked like:

The user initially attempted to split the text response into individual variables using the .split() method, which led to unnecessary complexity. They realized that a better solution would be to convert the text response directly into a JSON array to facilitate looping through API requests.

The Solution: Transforming Text to JSON Array

To solve this problem, you can use the Postman scripting feature to process the response text effectively. Below are the steps you'll need to follow to convert the text response into a JSON array.

Step-by-Step Instructions

Retrieve the Response Text: Use pm.response.text() to get the text response from the API call.

Create a JSON Object: Initialize an empty object where each UUID will be stored.

Iterate Over the Response: Use a loop to go through each element in the response, and assign each UUID to a key in the JSON object.

Conclusion

Transforming a plain text response into a JSON array can significantly simplify your API interactions and help in managing requests more dynamically. By following the steps outlined above, you can easily convert the responses you get in Postman into a more structured format, which opens up new possibilities for your API testing and documentation efforts.

Now you can say goodbye to the challenges of handling raw text responses and embrace the structured power of JSON! Happy coding!
