Importing Data into Memgraph from a Remote JSON File

If you've been using Memgraph, you may already know how to import data from a local JSON file. But what if your JSON file resides on a remote server? Can you still load that data efficiently? The answer is yes! In this guide, we will show you how to import data into Memgraph from a remote JSON file using simple queries.

Understanding the Process

Importing data into Memgraph from a remote location can be achieved by using a specific procedure that allows you to specify the accessible URL of your JSON file. This means that as long as you have the proper URL and your file is formatted correctly, you can easily integrate external data into your Memgraph database.

Example JSON File Structure

Before diving into the steps, let’s take a look at a simple example of what our JSON file might look like:

This structured data represents a person with their name and pets, which we will import into Memgraph.

Step-by-Step Import Process

Step 1: Replace the Argument in the Procedure

To load JSON files from any local or remote location, you simply need to modify the argument of the procedure with the proper path or URL leading to your JSON file.

Step 2: Crafting the Import Query

Now, let's create a Memgraph query that will help us import our JSON data correctly.

Below is the query you can use to create a node with the label Person and set properties such as first_name, last_name, and pets from the given data.json file:

Breakdown of the Query

CALL json_util.load_from_url("YOUR_URL"): This part is where you specify the URL to your remote JSON file.

YIELD objects: This command returns the data contained within the JSON file.

UNWIND objects AS o: This operation transforms your objects into a row format that can be processed individually.

CREATE (:Person { ... }): Here, we create a new node labeled Person with properties extracted from the JSON data.

Conclusion

Importing data into Memgraph from a remote JSON file is a straightforward process when you know the right steps and procedures to follow. By simply using the json_util.load_from_url function, you can seamlessly integrate external data into your Memgraph database.

Feel free to customize the query to match your specific data structure and requirements. Happy importing!
