How to concatenate (merge) two JSON arrays

Hey there! In this guide, we'll walk through how to use Xano's powerful visual interface to concatenate two JSON arrays into a single array. This can be incredibly useful when working with data from multiple sources or when you need to combine data for further processing or display.

Step 1: Create a New API

First, let's create a new API in Xano. Give it a descriptive name, such as "JSON Array Concatenation."

Step 2: Add Input Parameters

Next, we'll add two input parameters to our API, one for each JSON array we want to concatenate.

1. Click the "Add Input" button.
2. Select the "List" data type.
3. Name this input "listA" and click "Save."
4. Repeat the process and create another input called "listB" of the "List" data type.

Step 3: Set Up the Response

Now it's time to define the response we want our API to generate. In this case, we want to return a single array that combines the elements from both input arrays.

1. In the "Response" section, click the "Select Input" button and choose "listA."
2. Next, click the "Add Filter" button and select the "merge" operation.
3. Click the "Select Input" button again and choose "listB."
4. Click "Update" to save your changes.

Step 4: Test Your API

With everything set up, it's time to test our API and see it in action!

1. Click the "Run" button in the top-right corner of the Xano interface.
2. In the "Input Values" section, enter your sample JSON arrays for "listA" and "listB." For example:

1. Click "Run" again, and you should see the concatenated array in the "Response" section.

Just like that, you've successfully combined two JSON arrays using Xano's intuitive visual interface!

Why Use Xano for JSON Array Concatenation?

Concatenating arrays is a common operation in web and mobile app development, but it can be tedious to write and maintain code for this task. With Xano, you can achieve the same result without writing a single line of code, saving you time and effort.

Xano's visual interface makes it easy to understand and modify your data transformations, even for non-technical users. This can be particularly useful for citizen developers, startups, and small businesses that may not have dedicated development resources.

Additionally, Xano allows you to integrate this functionality seamlessly into your backend services, making it easy to build and deploy robust APIs for your applications.

So, whether you're a no-code enthusiast, a citizen developer, or an experienced developer looking to streamline your workflow, give Xano a try for your JSON array concatenation needs!
