Example: Extract Text from a PDF (C#)

To extract text from a single PDF file using Aspose.PDF, follow this example:

using Aspose.Pdf.Plugins;

var extractor = new TextExtractor();
var options = new TextExtractorOptions(TextExtractorOptions.TextFormattingMode.Pure);
options.AddInput(new FileDataSource("C:\\Samples\\sample.pdf"));
var resultContainer = extractor.Process(options);
string extractedText = resultContainer.ResultCollection[0].ToString();
Console.WriteLine(extractedText);

Example: Batch Extract Text from Multiple PDFs

For batch processing of multiple PDF files, use the following example:

string[] pdfFiles = { "sample1.pdf", "sample2.pdf" };
var extractor = new TextExtractor();
var options = new TextExtractorOptions(TextExtractorOptions.TextFormattingMode.Raw);
foreach (var file in pdfFiles)
{
options.AddInput(new FileDataSource(file));
}
var resultContainer = extractor.Process(options);
for (int i = 0; i < resultContainer.ResultCollection.Count; i++)
{
string text = resultContainer.ResultCollection[i].ToString();
Console.WriteLine(text);
}

Use Cases & Extensions

  • PDF to TXT Conversion: Automate conversion of PDFs to plain text for indexing, search, or archival.
  • Data Mining: Extract table data, invoices, or forms for further processing or analytics.
  • Accessibility: Prepare readable content for screen readers or alternate formats.
  • Batch Processing: Use extraction modes for specific downstream workflows (e.g., OCR pre-processing, entity recognition).

Best Practices

Always select the appropriate extraction mode based on your output requirements. For large document sets, batch processing can maximize throughput and minimize manual effort. Test extraction results with real-world PDFs to ensure data accuracy.
