Features and Functionalities

PDF to Excel Conversion

  • Convert each PDF page into a separate worksheet or merge multiple pages into one.
  • Output to .xls or .xlsx formats.

Page and Range Selection

  • Convert full documents or specific ranges/pages.
  • Supports non-contiguous ranges for selective extraction.

Layout and Formatting Preservation

  • Retains fonts, colors, cell borders, merged cells, and headers/footers.
  • Ensures Excel output mirrors PDF visual fidelity.

Table Recognition

  • Detects and reconstructs tabular data into Excel rows/columns.
  • Preserves numeric formats (currency, percentages, dates) for accurate calculations.

Password-Protected PDFs

  • Supports conversion of encrypted PDFs by supplying credentials at runtime.

Fonts and Resources

  • Embedded fonts are carried over into Excel.
  • Substitutions maintain layout if a font is unavailable.

Performance Optimization

  • Stream-based conversion processes pages incrementally.
  • Caching and buffer size control improve throughput on large files.

Error Handling and Logging

  • Detailed exceptions for unsupported content or malformed input.
  • Logging hooks to capture progress, warnings, and errors.

Thread Safety and Async Support

  • Supports concurrent conversions in multi-threaded environments.
  • Asynchronous methods for scalable workloads.

Code Example: Converting PDF to XLS (Excel) 

var inputPath = Path.Combine(@"C:\\Samples\\", "sample.pdf");
var outputPath = Path.Combine(@"C:\\Samples\\", "sample.xlsx");

// Initialize the plugin
var plugin = new PdfXls();
var options = new PdfToXlsOptions
{
    Format = PdfToXlsOptions.ExcelFormat.XLSX
};

options.AddInput(new FileDataSource(inputPath));
options.AddOutput(new FileDataSource(outputPath));

var resultContainer = plugin.Process(options);
var result = resultContainer.ResultCollection[0];
Console.WriteLine(result);

Tips and Best Practices

  • Pre-scan PDFs to detect tabular vs. text content for optimized conversion.
  • Use page ranges to minimize unnecessary processing.
  • Dispose of converter instances to release unmanaged resources.
  • In bulk operations, use async APIs with controlled parallelism.
  • Validate numeric formats in test runs before deployment.
  • Monitor logs for unsupported features or malformed inputs.
  • Embed non-standard fonts to prevent layout mismatches.
  • Keep the plugin updated for accuracy and performance improvements.

Advanced Features

  • Batch conversion of multiple PDFs simultaneously.
  • Encrypt resulting Excel files for secure distribution.
  • Customizable output layouts tailored to reporting or compliance requirements.

Use Cases

  • Financial reporting by extracting tables into Excel for analysis.
  • Data migration from static PDF archives into editable Excel sheets.
  • Automated workflows for compliance and auditing.
  • Bulk tabular data extraction from invoices, statements, or forms.
