JSLTSharp 1.2.0

JSLTSharp

This library let you to apply some transformations on a json object. Like an xslt document, transform a json string to another

I have created this library in .NET which enables the transformation of JSON documents using very a simple transformation language like an xslt transformation for XML document, but for JSON. I've also created this package as the excellent https://github.com/WorkMaze/JUST.net package does not responds exactly to my needs, and in case of big volumetry of data, performances was not good for my needs.

Onboarding Instructions

Installation

1. Add nuget package:

Install-Package JSLTSharp

2. In your application, you must instanciate a new JsonTransform object, and call the method 'Transform' to transform your json:

var input = @"{
        'field1': 13246.51,
        'field2': true
    }";
    
var transformation = @"{
        'resultField1': '$.field1->ToInteger()',
        'resultField2': '$.field2'
    }";

var transformEngine = new JsonTransform();
var result = transformEngine.Transform(input, transformation);

result value :

{
    "resultField1": 13246,
    "resultField2": true
}

Selectors

In your transformation description, you can refers to fields by using a JsonPath expression

Ex :

{
    "resultField1": "$.field1->ToInteger()",
    "resultField2": "$.field2"
}

$.field1 refers to to the property named field1 on the json input.

ℹ️ If you have to test your selector, you can use the online tool https://jsonpath.com/.

Create my own function

The package can be extended by using your own functions. Code your own C# function, and register it on the service collection of your application. More details on the Wiki.

Do not hesitate to check unit tests on the solution. It's a good way to check how transformations are tested.
