Acquire a free trial or temporary license from the GroupDocs website for full functionality. Consider purchasing a license for long-term use.

Basic Initialization and Setup

Initialize GroupDocs.Conversion in your .NET project with this setup:

using GroupDocs.Conversion;

// Define the document directory path
string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";

// Combine with source file name
string sourceFilePath = System.IO.Path.Combine(documentDirectory, "sample.otg");

Implementation Guide

Load OTG File

Overview: This step involves loading your OTG file using GroupDocs.Conversion.

Step 1: Define Document Directory

// Set the path to your document directory
string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";

Replace YOUR_DOCUMENT_DIRECTORY with your actual OTG files’ storage path.

Step 2: Combine Path with Source File Name

// Construct full path to the source file
string sourceFilePath = System.IO.Path.Combine(documentDirectory, "sample.otg");

Step 3: Load the OTG File

using (var converter = new Converter(sourceFilePath))
{
    // The OTG file is now loaded and ready for further processing.
}

This snippet creates a Converter object to load your OTG file, preparing it for conversion.

Set Conversion Options to XLSX

Overview: Configure the conversion process to output an XLSX file.

using GroupDocs.Conversion.Options.Convert;

// Create an instance of SpreadsheetConvertOptions
var options = new SpreadsheetConvertOptions();

These settings configure the conversion process for XLSX format.

Save Converted File as XLSX

Overview: This step involves saving your converted OTG file in XLSX format.

Step 1: Define Output Directory and Path

// Set the output directory path and name for the converted file
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string outputFile = System.IO.Path.Combine(outputDirectory, "otg-converted-to.xlsx");

Step 2: Convert and Save

using (var converter = new Converter(sourceFilePath))
{
    var options = new SpreadsheetConvertOptions();
    converter.Convert(outputFile, options);
}
// The OTG file is now converted and saved as 'otg-converted-to.xlsx' in the specified output directory.

This code converts the loaded OTG file into XLSX format using the defined conversion options.

Troubleshooting Tips

  • Ensure your source file path is correct to avoid FileNotFoundException.
  • Verify that your output directory exists or create it programmatically if necessary.
  • For persistent issues, consult the GroupDocs documentation for further guidance.
