Extract Key-Value Pairs Using C#


PSPDFKit Processor has been deprecated and replaced by PSPDFKit Document Engine. All PSPDFKit Processor licenses will work as before and be supported until 15 May 2024 (we will contact you about license migration). To start using Document Engine, refer to the migration guide. With Document Engine, you’ll have access to robust new capabilities (read the blog for more information).

Automatically detect and extract key-value pairs from unstructured documents or images with our native SDK. Leveraging AI, ML, and adaptive layout understanding, the key-value pair (KVP) engine is used to reduce manual and repetitive document processing tasks. It can automatically label and extract information such as phone numbers, IBANs, credit cards, names, and email addresses from unstructured or semi-structured documents. The engine recognizes KVPs in all supported OCR languages. Explore our guides and code samples to learn how you can quickly integrate our KVP technology into your application or workflow.

Launch Demo

PSPDFKit SDKs are deployed in some of the world’s most popular applications, such as those made by Autodesk, Disney, DocuSign, Dropbox, IBM, and Lufthansa.
