Convert table rows to JSON in X++ D365

To convert table rows to JSON in X++, you can use the JSON serialization capabilities provided by X++'s built-in classes. Here's an example demonstrating how to achieve this:
 
Assuming you have a table named MyTable with fields Field1, Field2, and Field3, and you want to convert its rows to a JSON array:
 
static void ConvertTableRowsToJson(Args _args)
{
    MyTable myTable;
    str jsonString;
    int i;
 
    // Create an empty array to store JSON objects
    Array jsonArray = [];
 
    // Retrieve data from the table
    while select * from myTable
    {
        // Create a JSON object for each row
        JsonObject jsonObject = new JsonObject();
        jsonObject.addField("Field1", myTable.Field1);
        jsonObject.addField("Field2", myTable.Field2);
        jsonObject.addField("Field3", myTable.Field3);
 
        // Add the JSON object to the array
        jsonArray.value(++i, jsonObject);
    }
 
    // Convert the array to a JSON string
    jsonString = jsonArray.toJson();
 
    info(jsonString);
}
 
This example uses the JsonObject and JsonArray classes available in X++ to create a JSON array containing JSON objects for each row in the MyTable table. The toJson method is then used to convert the array to a JSON string.
 
Make sure to adjust the code according to your actual table structure and field names. Additionally, ensure that your X++ environment supports the JsonObject and JsonArray classes.
