Implementation Guide

Let’s go through the process of converting a .dotx file into an XLSX format using GroupDocs.Conversion.

Feature 1: Load Source DOTX File

Overview

Loading your source DOTX file is essential for preparing it for conversion.

Step 1: Define Document Path and Load the File
using System;
using System.IO;
using GroupDocs.Conversion;

public class FeatureLoadSourceDotx
{
    public void Execute()
    {
        // Define the path to your input documents
        string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
        
        // Construct the full path for the source DOTX file
        var sourceFilePath = Path.Combine(documentDirectory, "sample.dotx");
        
        // Load the DOTX file using GroupDocs.Conversion
        using (var converter = new Converter(sourceFilePath))
        {
            // The conversion object is now ready to perform conversions
            Console.WriteLine("DOTX file loaded successfully.");
        }
    }
}
  • Parameters: sourceFilePath points to your .dotx file.
  • Return Values: No direct return value, but the Converter object allows further actions.

Feature 2: Convert DOTX to XLSX

Overview

With your source document loaded, proceed to convert it into an Excel spreadsheet format (XLSX).

Step 1: Set Output Directory and Define Conversion Options
using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

public class FeatureConvertDotxToXlsx
{
    public void Execute()
    {
        // Specify the output directory for converted documents
        string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
        
        // Define the path where the XLSX file will be saved
        var outputFilePath = Path.Combine(outputDirectory, "dotx-converted-to.xlsx");
        
        // Load the source DOTX file (assuming it was loaded previously)
        string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
        var sourceFilePath = Path.Combine(documentDirectory, "sample.dotx");

        using (var converter = new Converter(sourceFilePath))
        {
            // Create conversion options for XLSX format
            var options = new SpreadsheetConvertOptions();
            
            // Convert and save the file as XLSX
            converter.Convert(outputFilePath, options);
            Console.WriteLine("Conversion to XLSX completed successfully.");
        }
    }
}
  • Parameters: outputFilePath is where your converted document will reside.
  • Configuration Options: The SpreadsheetConvertOptions class provides various settings for the conversion process.
