Extract Key-Value Pairs Using C#

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.

As a native SDK, it can be deployed on-premises or embedded in your application, and it works offline, without internet access. Integration is simple and doesn’t require specific types of CPUs or a complex server infrastructure. Explore our guides and code samples to learn how you can quickly integrate our KVP technology into your C# 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.
