Form Recognizer SDK (c#)

I have multiple PDFs, each with different form fields (Textbox, checkbox etc.)

Using the API is there a way to iterate through form fields in a PDF and return the type (textbox, checkbox etc.)

And if Is so which prebuilt-model would offer this functionality?

Thanks in advance

    Hi @Adam-6651

    Regarding "Using the API is there a way to iterate through form fields in a PDF and return the type (textbox, checkbox etc.)"

    you could use a custom model for a better defined output.

    The challenge is you need to identify it, mark in the form and train the model. you need at least 5 different types of the same model

    it will return an array like this:

    There are 3 options for pre-built Document analysis :

    "Layout" mentions extract check boxes but the output is a bit difficult to process, the result for the checkboxes appeared seaparated from the labels, but may be a question of relating it:

    "General Documents" can let you flag checkboxes when it returns "selected" or "unselected" . Data is not as good as trained model but you don't need to create the model:
