rapidjson | fast JSON parser/generator for C++ with both SAX/DOM style | JSON Processing library

I want to make a function that returns a constructed rapidjson::Value from it. Like this:

I'm making a physical software and we deploy a json solution and I wanted to used json schema. So, when I had a wrong key typical looking a "length" in the schema and the user gives somethings wrong like "length2". I don't know how to get it with rapidjson actually, I obtained these results

I want to read a JSON document with RapidJSON. My JSON document contains a multi-dimensional matrix and has the following form:

The following is a JSON file exported from Tiled Map Editor.

I needed to pass a variable with rapidjson::Value type to another function with the following code:

I'm using cereal to serialize and deserialize data in c++, and I came upon a problem. I'm sending data using a socket to the client side, so i send a stringstream with the serialized files in a JSON format. The problem is that I can't deserialize it with simple data types, nor with complex ones, on the client side as it fails a rapidjson check and it tells me it's not an object

What would be the proper way of deserializing data considering that i can't create an instance of a class from the server side ?

Here is a simple example in which i try to send the username of a user to the client side

The send function :

Hello I have nested json files with size of 400 megabytes with 200k records.I created a solution using pyspark to parse the file and store in a customized dataframe , but it takes about 5-7 minutes to do this operation which is very slow.

Here is an example of a json file (small one but with same structure as the large ones) :

I need to put a stringstream as a value of a JSON (using rapidjson library), but std::stringstream::str is not working because it is not returning UTF-8 characters. How can I do that?

Example: d["key"].SetString(tmp_stream.str());

I'm currently sending rapidjson::Value of array type called databuf to a websocket from boost library.

Here is how I load databuf at each loop.
