You can use LEADTOOLS Document or Recognition SDK technology in your application. https://www.leadtools.com/sdk/products/recognition You can leverage the OcrPage class to extract the text from a searchable document. See the tutorial in the below link for how to extract text from a PDF and export those results to JSON file. https://www.leadtools.com/help/sdk/v21/tutorials/dotnet-console-export-ocr-results-to-json.html The tutorial in the link above uses C# in a .NET Framework console application, and the code should easily be used inside an ASP.NET application without MVC.
