Welcome to the GroupDocs.Parser for .NET
GroupDocs.Parser is a convenient text extractor API that permits users to extract raw or formatted text from different document formats. Besides, it is not only a text extractor API, the user can extract metadata from the document as well.

GroupDocs.Parser for .NET is a powerful document data extraction API that enables developers to parse and extract information from over 50 document types. This robust library allows you to extract text, metadata, images, tables, and other structured data from various file formats without requiring additional software installations.

• Multiple Extraction Modes - Raw text, formatted text, and precise data extraction
• Enterprise Ready - Scalable solution for high-volume document processing
• Cross-Platform - Compatible with .NET Framework, .NET Core, and .NET 5+

One of the most powerful features is parsing documents with predefined templates. Easily define templates to extract specific data from invoices, receipts, contracts, and other structured documents with high precision.

• Raw Text Mode - Fast extraction for basic text processing
• Formatted Text Mode - Preserve document formatting and structure
• Search & Highlight - Advanced text search with regex support and keyword highlighting

• Extract images and save them in various formats

    {
        // Check if text extraction is supported
        if (reader != null)
        {
            // Print the extracted text
            Console.WriteLine(reader.ReadToEnd());
        }
        else
        {
            Console.WriteLine("Text extraction isn't supported for this format");
        }

Create custom templates to extract specific data fields:

// Create a template with fixed positions
Template template = new Template(new TemplateItem[]
{
    new TemplateField(new TemplateFixedPosition(new Rectangle(new Point(35, 135), new Size(100, 10))), "CompanyName"),
    new TemplateField(new TemplateFixedPosition(new Rectangle(new Point(35, 150), new Size(100, 10))), "InvoiceNumber")
});

// Parse document using template
using (Parser parser = new Parser("invoice.pdf"))
{
    DocumentData data = parser.ParseByTemplate(template);
    // Process extracted data
}

Process multiple documents efficiently:

string[] files = Directory.GetFiles(@"C:\Documents", "*.*");
foreach (string file in files)
{
    using (Parser parser = new Parser(file))
    {
        // Extract and process data from each file
        using (TextReader reader = parser.GetText())
        {
            if (reader != null)
            {
                string content = reader.ReadToEnd();
                // Process the content
            }
        }
    }
}
