Implementation Guide

Feature: Load DJVU File

Overview

Loading a DJVU file is the first step in conversion. This section covers how to initialize and prepare your file for transformation using GroupDocs.Conversion.

Step 1: Define the Input Path

Specify where your DJVU file resides:

string inputFilePath = "YOUR_DOCUMENT_DIRECTORY\sample.djvu";
Step 2: Initialize Converter Instance

Create a new Converter instance with your DJVU file path:

using (var converter = new Converter(inputFilePath))
{
    // Your file is now loaded and ready for conversion.
}

Feature: Configure Conversion Options

Overview

Configuring the correct options ensures your document converts correctly into an XLS format.

Step 1: Create SpreadsheetConvertOptions

Set up the conversion options targeting XLS:

var options = new SpreadsheetConvertOptions();
options.Format = GroupDocs.Conversion.FileTypes.SpreadsheetFileType.Xls;

Feature: Save Converted File

Overview

The final step is saving your converted file in your desired directory with a specified format.

Step 1: Define Output Directory and Path

Ensure the output directory exists, then define where to save the converted file:

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
Directory.CreateDirectory(outputFolder);
string outputFile = Path.Combine(outputFolder, "djvu-converted-to.xls");
Step 2: Perform Conversion and Save File

Using the previously set up Converter instance and conversion options, save your converted file:

using (var converter = new Converter("YOUR_DOCUMENT_DIRECTORY\sample.djvu"))
{
    var options = new SpreadsheetConvertOptions { Format = GroupDocs.Conversion.FileTypes.SpreadsheetFileType.Xls };
    
    // Convert and save the output file.
    converter.Convert(outputFile, options);
}

Practical Applications

  1. Automating Document Workflows: Integrate this conversion process into automated systems to streamline document handling in enterprises.
  2. Data Migration Projects: Utilize the conversion for migrating documents from legacy DJVU formats to modern spreadsheet applications.
