Extract data with GroupDocs.Parser Leave feedback
On this page
GroupDocs.Parser pulls content out of documents — plain text, formatted text, images, metadata, hyperlinks, tables and barcodes — across PDF, Word, spreadsheets, presentations, email, ebooks and archives. It is the usual first step when feeding documents to a search index or a language model.
GetText returns a TextReader. It returns null rather than throwing when the format does not support text extraction, so check it.

using System.IO;
using GroupDocs.Parser;
using (Parser parser = new Parser("contract.pdf"))
{
using (TextReader reader = parser.GetText())
{
if (reader == null)
{
Console.WriteLine("Text extraction is not supported for this format.");
}
else
{
Console.WriteLine(reader.ReadToEnd());
}
}
}

Formatted extraction keeps the document’s structure — headings, lists, emphasis — instead of flattening it. Markdown is the format to ask for when the text is destined for a language model.

NoteFormatted extraction is not available for every format — PDF returnsnullfromGetFormattedText, where plainGetTextworks fine. That is why the snippet checks the reader instead of assuming it. Word documents support Markdown, HTML and plain-text modes.
GetDocumentInfo reports the page count and format before you commit to extracting anything.

using GroupDocs.Parser.Options;
using (Parser parser = new Parser("contract.pdf"))
{
IDocumentInfo info = parser.GetDocumentInfo();

GroupDocs.Parser also extracts images, hyperlinks, tables of contents and barcodes, parses structured data with user-defined templates, reads PDF form values, and reaches into email attachments and ZIP archives.
