Implementation Guide

Loading Options for Spreadsheet Documents

Overview

Setting advanced loading options allows you to tailor how your spreadsheet documents are handled during conversion. This includes showing grid lines and ensuring each sheet is converted as a separate page.

Implementing the Feature

Here’s how you can configure these options:

import com.groupdocs.conversion.options.load.SpreadsheetLoadOptions;

public class LoadSpreadsheetWithOptions {
    public static void run() {
        SpreadsheetLoadOptions loadOptions = new SpreadsheetLoadOptions();
        
        // Show grid lines in the converted document
        loadOptions.setShowGridLines(true);
        
        // Ensure each sheet is on a separate page
        loadOptions.setOnePagePerSheet(true);
    }
}
  • SpreadsheetLoadOptions: This class provides various configuration options for loading spreadsheets.
  • setShowGridLines(true): Enables grid lines in the output PDF.
  • setOnePagePerSheet(true): Converts each sheet into a separate page.

Conversion of Spreadsheet Document to PDF

Overview

With your load options set, you can proceed to convert your spreadsheet document to a PDF file using specific conversion settings.

Implementing the Feature

public class ConvertSpreadsheetToPdf {
    public static void run(String inputFilePath, String outputFilePath) {
        SpreadsheetLoadOptions loadOptions = new SpreadsheetLoadOptions();
        loadOptions.setShowGridLines(true);
        loadOptions.setOnePagePerSheet(true);
        
        Converter converter = new Converter(inputFilePath, () -> loadOptions);
        PdfConvertOptions options = new PdfConvertOptions();
        
        converter.convert(outputFilePath, options);
    }
