@Vikas M With pre built models you cannot modify the model behavior to create separate structure in the resulting output response. You can however have a query field extraction with certain prebuilt models.
Another option is to use custom model to train the model with all the required formats and then use the extracted result in your client application. You also have an option to create table field or tag to read certain data of a larger table and save it in this tag. But if the format varies frequently you will have to train several models to extract all the relevant data.
If the current pre-built model works well, try using the output of this response in your client application to build the required table format. If your forms use a uniform header then it should be easy for you to use this data from the response and build on top of it in your client application.
