[QUERY] FormRecognizer - Serialization for RecognizedFormCollection

Query/Question What is the correct way to handle serializing/deserializing Form Recognizer responses to and from JSON format using the Azure SDK? I am using Newtonsoft and attempting to serialize the RecognizedFormCollection for future processing as the FormField class contains methods to operate on the data that is loaded into the model, however, the class constructors are marked internal and as such cannot be deserialized directly. What is the correct way to handle this scenario?

https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/formrecognizer/Azure.AI.FormRecognizer/src/RecognizedFormCollection.cs

Environment:

• Name and version of the Library package used: [e.g. Azure.Storage.Blobs 12.2.0] Form Recognizer 3.2
• Hosting platform or OS and .NET runtime version (dotnet --info output for .NET Core projects): [e.g. Azure AppService or Windows 10 .NET Framework 4.8] .NET 5
• IDE and version : [e.g. Visual Studio 16.3] VS2019

Hello,

No. What I am trying to do is execute Form Recognizer which returns a RecognizedFormCollection. Once I have that object, I would like to export it as a json string somewhere (ex. Json File) as I will need to process it at a later time. Once I decide later on to to process it, I would like to deserialize the json back into a new RecognizedFormCollection and then use the methods such as field.Value.GetConvertedValue(); to pull out the values.

Given that RecognizedFormCollection does not support constructors, how am I supposed to load the data into the class properly?

Recreating the structure of RecognizedForm is not ideal.

For sure. That is why the SDK is in charge of that. So the user doesn’t have to.

I am re-opening the issue and will add it to triage.
