Implementation Guide

Load Source File

The first step in our conversion process involves loading the CMX file using GroupDocs.Conversion for .NET. This step is crucial as it prepares the document for subsequent operations.

Step 1: Define Path and Create Converter Instance

using System;
using System.IO;
using GroupDocs.Conversion;

namespace GroupDocs.Conversion.Examples.CSharp.BasicUsage
{
    internal static class LoadCmxFile
    {
        public static void Run()
        {
            // Define the path to your CMX file
            string inputFilePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample.cmx");

            // Create a new Converter instance for loading the CMX file
            using (var converter = new GroupDocs.Conversion.Converter(inputFilePath))
            {
                // The file is now loaded and ready for conversion operations
            }
        }
    }
}

Here, we define the path to our source CMX file and initialize a Converter object. This setup allows us to access various document conversion features provided by GroupDocs.

Define Conversion Options

Next, configure your conversion settings to specify that you want to convert the document into XLS format.

Step 2: Create Spreadsheet Convert Options

using GroupDocs.Conversion.Options.Convert;

namespace GroupDocs.Conversion.Examples.CSharp.BasicUsage
{
    internal static class SetConversionOptions
    {
        public static SpreadsheetConvertOptions CreateOptions()
        {
            // Define the conversion options for converting to an Excel file (XLS)
            var options = new SpreadsheetConvertOptions();
            
            // Specify that the target format should be XLS
            options.Format = GroupDocs.Conversion.FileTypes.SpreadsheetFileType.Xls;
            
            return options;
        }
    }
}

In this step, we create SpreadsheetConvertOptions and set the desired output format to XLS. This ensures your file is converted correctly into an Excel-compatible spreadsheet.

Perform Conversion

Now that our document is loaded and conversion parameters are defined, it’s time to execute the transformation.

Step 3: Convert CMX to XLS

using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

namespace GroupDocs.Conversion.Examples.CSharp.BasicUsage
{
    internal static class ConvertCmxToXls
    {
        public static void Run()
        {
            // Define the output directory and file path for the converted XLS file
            string outputFolder = "YOUR_OUTPUT_DIRECTORY";
            string outputFile = Path.Combine(outputFolder, "cmx-converted-to.xls");

            // Load the source CMX file
            using (var converter = new GroupDocs.Conversion.Converter("YOUR_DOCUMENT_DIRECTORY\\sample.cmx"))
            {
                // Create conversion options for XLS format
                var options = SetConversionOptions.CreateOptions();

                // Perform the conversion and save the output as an XLS file
                converter.Convert(outputFile, options);
            }
        }
    }
}

This final step loads your CMX file again (if needed), applies the conversion settings, and outputs the result as an XLS file. With this code, you’ve successfully completed the conversion process.

Practical Applications

GroupDocs.Conversion for .NET isn’t limited to converting CMX to XLS; it supports numerous applications:

  1. Data Migration: Seamlessly migrate legacy data from CMX files into modern Excel spreadsheets.
