Implementation Guide

Follow these steps to convert a PDF file into TXT format.

1. Define Directories for Input and Output Files

Specify the directories for your source PDF and output TXT files:

string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";

// Ensure directories exist or create them
if (!Directory.Exists(documentDirectory)) Directory.CreateDirectory(documentDirectory);
if (!Directory.Exists(outputDirectory)) Directory.CreateDirectory(outputDirectory);

2. Load and Prepare the Source PDF File

Load your source PDF file using the Converter class:

string sourceFilePath = Path.Combine(documentDirectory, "sample.pdf");
string outputFile = Path.Combine(outputDirectory, "pdf-converted-to.txt");

using (var converter = new GroupDocs.Conversion.Converter(sourceFilePath))
{
    // Conversion will happen in the next step
}

3. Set Conversion Options and Perform Conversion

Configure the conversion options for TXT format and execute the conversion:

// Use WordProcessingConvertOptions for text format conversion
WordProcessingConvertOptions options = new WordProcessingConvertOptions 
{ 
    Format = GroupDocs.Conversion.FileTypes.WordProcessingFileType.Txt 
};

// Execute conversion and save to output file path
converter.Convert(outputFile, options);

Troubleshooting Tips

  • PDF not found: Ensure the source PDF exists in the specified directory.
  • Permission issues: Verify your application has write access to the output directory.

Practical Applications

Consider these real-world scenarios for converting PDFs to TXT:

  1. Data Extraction: Extract text from scanned documents for further processing.
  2. Text Analytics: Perform text analysis and sentiment evaluation on document content.
  3. Compatibility: Ensure compatibility of text data across systems requiring plain text.

GroupDocs.Conversion can be easily integrated with other .NET frameworks like ASP.NET or Xamarin, enhancing its utility in diverse applications.
