JSON Visualisation with PlantUML

While JSON is a versatile and widely used data format, understanding the structure and relationships within a complex JSON file can be quite challenging. This is where PlantUML can be a game-changer, helping you visualise JSON structures effectively.

Here's a quick guide on visualising JSON structures:

Step 1: Understand the JSON Structure

Let's take this JSON data for a blog post as an example:

{
  "title": "My First Blog Post",
  "author": "John Doe",
  "date": "2023-01-01",
  "tags": ["PlantUML", "Tutorial"],
  "comments": [
    {
      "user": "Jane",
      "message": "Great post!",
      "date": "2023-01-02"
    },
    {
      "user": "Tom",
      "message": "Very helpful",
      "date": "2023-01-03"
    }
  ]
}

Step 2: Map the JSON Structure to a Diagram

PlantUML offers a straightforward approach to convert JSON structures into diagrams using the @startjson and @endjson tags:

@startjson
{
  "title": "My First Blog Post",
  "author": "John Doe",
  "date": "2023-01-01",
  "tags": ["PlantUML", "Tutorial"],
  "comments": [
    {
      "user": "Jane",
      "message": "Great post!",
      "date": "2023-01-02"
    },
    {
      "user": "Tom",
      "message": "Very helpful",
      "date": "2023-01-03"
    }
  ]
}
@endjson

This code generates a diagram representing the structure of the BlogPost object, complete with the relationships between different components. For example, it clearly shows that each BlogPost has multiple comments, each with a user, message, and date.

By visualising JSON data this way, you can more easily understand complex structures and relationships, which simplifies the process of working with APIs, config files, and more.
