Implementation Guide

Load Spreadsheet with Hidden Sheets

Overview: This feature demonstrates how to load spreadsheets, ensuring that hidden sheets are included during the conversion process.

Step 1: Define Load Options

Start by creating a function to define your load options:

Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new SpreadsheetLoadOptions
{
    ShowHiddenSheets = true,
    OnePagePerSheet = true
};
  • ShowHiddenSheets: Ensures hidden sheets are processed.
  • OnePagePerSheet: Each sheet is converted to a single PDF page.

Overview: This section covers converting your loaded spreadsheet into a PDF file while applying specific conversion settings for optimized output.

Step 2: Set Up Conversion Parameters

Specify the desired output location and initialize the converter:

using System.IO;
using GroupDocs.Conversion.Options.Convert;

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "converted.pdf");

// Initialize Converter with load options.
using (Converter converter = new Converter("path/to/your/document.xlsx", getLoadOptions))
{
    // Define conversion settings for PDF.
    var convertOptions = new PdfConvertOptions();

    // Perform the conversion.
    converter.Convert(() => File.Create(outputFile), convertOptions);
}
  • Output Directory: Ensure your output path is valid and writable.
  • PdfConvertOptions: Customize these to tweak the PDF’s appearance.

Troubleshooting Tips

  • Ensure hidden sheets are present in your document by checking it manually before conversion.
  • Validate file paths for both input and output directories to avoid runtime errors.

Practical Applications

GroupDocs.Conversion can be integrated into various .NET applications, such as:

  1. Automated Report Generation: Convert financial or statistical reports stored in Excel files directly into shareable PDFs.

  3. Data Archiving Solutions: Preserve data integrity by converting spreadsheets to a non-editable format like PDF.

Performance Considerations

  • Resource Usage: Monitor CPU and memory usage, especially when processing large files.
  • Memory Management: Dispose of objects properly using using statements for efficient resource management.
  • Batch Processing: For multiple file conversions, consider parallelizing tasks while keeping system limits in mind.
