Converting a document from XLSX to PDF format

Converting Excel files (XLSX) to PDF — whether for auditing, legal purposes, or archiving — ensures critical data is preserved in a tamper-proof form that maintains its original appearance.

How Nutrient helps you achieve this

Nutrient .NET SDK handles XLSX-to-PDF conversion. With the SDK, you don’t need to worry about:

• Parsing Excel file structures
• Managing spreadsheet layouts
• Handling cell formatting and styles
• Complex rendering logic

Instead, Nutrient provides an API that handles all the complexity behind the scenes, letting you focus on your business logic.

Complete implementation

Below is a complete working example that demonstrates XLSX-to-PDF conversion. This line sets up the C# application. The using directive brings in the Nutrient SDK namespace:

using Nutrient;

This line opens the Excel file. The using declaration(opens in a new tab) ensures the document is automatically closed when it goes out of scope, preventing resource leaks:

try
{
    using Document document = Document.Open("input.xlsx");

This block exports the document to PDF and saves it as output.pdf. The try-catch block handles potential errors using NutrientException:

    document.ExportAsPdf("output.pdf");
    Console.WriteLine("Successfully converted to output.pdf");
}
catch (NutrientException e)
{
    Console.Error.WriteLine($"Error: {e.Message}");
    Environment.Exit(1);
}

Conclusion

The conversion logic consists of two steps:

1. Open the document.
2. Export as PDF.

Nutrient handles Excel file parsing and PDF rendering so you don’t need to understand spreadsheet internals or manage complex layouts.
