Convert DOC (Word 97-2003) to Text format using C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Load an input document.
  3. Save to a Text format.

Document .Net can help your application to convert a document from a one format to another.
You'll need only to Load() a document and Save() to a desired format:


            DocumentCore dc = DocumentCore.Load(inpFile);
            dc.Save(outFile);

Document .Net supports these formats:

PDF DOCX RTF HTML Text Image
Create/Read/Write Create/Read/Write Create/Read/Write Create/Read/Write Create/Read/Write Create/Read(OCR)/Write
