Extract only specific data from invoice using amazon textract

Amazon Textract automatically detects the vendor name, invoice number, ship to address, and more from the sample invoice and displays them on the Summary Fields tab. It also represents the standard taxonomy of fields in brackets next to the actual value on the document. For example, it identifies “INVOICE #” as the standard field INVOICE_RECEIPT_ID.
