Converting a document from XLSX to PDF format

Convert Excel files to PDF when you need stable output for sharing, reporting, or archiving. This helps you:

  • Preserve spreadsheet layout and formatting
  • Avoid rendering differences across spreadsheet apps
  • Create fixed output for external distribution
  • Keep records in a long-term document format

Use the Java SDK for conversion

Use the Java SDK to convert XLSX files to PDF directly in your app workflow.

Preparing the project

Define a package and create a class for this conversion flow:

package io.nutrient.Sample;

Import Nutrient Java SDK classes. Prefer explicit imports for the classes you use:

import io.nutrient.sdk.Document;
import io.nutrient.sdk.exceptions.NutrientException;


public class ExcelDocumentToPDF {

Create a main method and declare NutrientException:

    public static void main(String[] args) throws NutrientException {

Then add the SDK-specific conversion logic.

Proceeding with the conversion

This guide uses the Document class. Initialize it with a try-with-resources statement(opens in a new tab) to close resources correctly.

Open source files by file path or stream. This example uses a file path:

        try (Document document = Document.open("input.xlsx")) {

After loading the file, call SDK methods on the document instance. For the full API surface, refer to the API reference.

Export the document as PDF. Write to a file path or stream. This example writes output.pdf to the working directory:

            document.exportAsPdf("output.pdf");
        }
    }
}

You now have a PDF file.

Error handling

The SDK throws NutrientException when conversion fails. Handle this exception in your app for custom logging, retries, or fallback logic.

Conclusion

You now have a complete XLSX-to-PDF conversion flow in Java. Download the sample package to run this example as-is.
