How to serialize complex object to JSON?

Question

C++ / C#

I want to store information about levels in separate files, and I can't figure out how to serialize such an object. As you understand the main trouble in the sheet (can be replaced with an array).

Answer 1

How do you understand the main trouble in the sheet (can be replaced with an array)

I don't understand what the problem is.

Both System.Text.Json and Newtonsoft.Json can serialize sheets out of the box.
The problem can only arise when using fields, instead of properties - then you just need to specify in the options that you need to include fields.

var obj = new TestObject { SomeField = "asd" };
JsonSerializer.Serialize(obj, new JsonSerializerOptions() { IncludeFields = true });
