Key Value pair return from OCR JASON


We are working on a project and want to use to extract text from certain type of document like aadhar, passport and voter id and bank statement and so. But once your system return json, there my team has to write modal and train them to identify the key value pair which we do not want to invest our time for now.

If there is anyway or api which can be used to find key value pair data from the information extracted from a specific type of document.

Please update.

Can you please post an example document/image?
