• Simple Workflow: Highlight the JSON in your editor, open the command palette, and generate your model.
• Automatic Class Name Suggestions: The extension can suggest class names based on file or selection context.

Using GUI

Configuration

You can customize the extension to fit your needs by editing your VS Code Settings (File > Preferences > Settings on Windows/Linux or Code > Preferences > Settings on macOS). Some potential configuration options might include:

• json2entity.outputFolder: Choose the folder where generated model files should be placed.
• json2entity.namingConvention: Select the naming convention for fields/properties (e.g., snake_case, camelCase, PascalCase).
• json2entity.overwriteExisting: If set to true, automatically overwrite existing model files with the same name.

(Adjust or remove this section if these settings are not yet implemented.)

Example

}

Java

public class ExampleModel {
    private int id;
    private String title;
    private Details details;

    // getters and setters
}

public class Details {
    private String author;
    private String createdDate;

    // getters and setters
}

Python

class ExampleModel:
    def __init__(self, id: int, title: str, details: 'Details'):
        self.id = id
        self.title = title
        self.details = details

class Details:
    def __init__(self, author: str, createdDate: str):
        self.author = author
        self.createdDate = createdDate

C#

public class ExampleModel
{
    public int Id { get; set; }
    public string Title { get; set; }
    public Details Details { get; set; }
}

public class Details
{
    public string Author { get; set; }
    public string CreatedDate { get; set; }
