In the realm of document processing in .NET applications, extracting text from various file formats is a common requirement. GroupDocs.Parser for .NET offers a powerful solution to seamlessly parse and extract text from a diverse range of documents. This tutorial will guide you through the process of utilizing GroupDocs.Parser to extract text from documents step by step.

Prerequisites

Before diving into using GroupDocs.Parser for .NET, ensure you have the following set up:

• Development Environment: Visual Studio or any other .NET development environment.
• GroupDocs.Parser for .NET Package: Download and install the GroupDocs.Parser for .NET library from here.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;

The following steps demonstrate how to extract text from a document using GroupDocs.Parser from a stream.

Step 1: Load Document from Stream

// Create the stream
using (Stream stream = File.OpenRead("YourSampleFile.docx"))
{
    // Create an instance of Parser class with the stream
    using (Parser parser = new Parser(stream))
    {
        // Extract text into the reader
        using (TextReader reader = parser.GetText())
        {
            // Print text from the document
            // If text extraction isn't supported, the reader will be null
            Console.WriteLine(reader == null ? "Text extraction isn't supported" : reader.ReadToEnd());
        }
    }
}

In this example:

• We open a file stream for the document file (YourSampleFile.docx).
• Initialize a Parser instance with the stream.
• Use parser.GetText() to retrieve a TextReader containing the extracted text.
• Print out the extracted text or a message if text extraction isn’t supported for the document format.

Conclusion
