Implementation Guide

Convert OST File to XLS

This feature demonstrates how you can convert an OST file into an Excel spreadsheet using GroupDocs.Conversion.

Overview

Converting OST to XLS allows for better data manipulation and analysis. This process involves loading the OST file, setting conversion options, and saving the output as an XLS file.

Step-by-Step Implementation

1. Specify File Paths First, define paths for your source OST file and the output directory:

string documentPath = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "sample.ost");
string outputPath = @"YOUR_OUTPUT_DIRECTORY";
string outputFileTemplate = Path.Combine(outputPath, "ost-converted-{0}-to.xls");

2. Load the Source File Load your OST file with specific load options for Outlook files:

using (var converter = new GroupDocs.Conversion.Converter(documentPath, new ConverterSettings() {
    LoadOptions = new PersonalStorageLoadOptions()
}))
{
    // Conversion logic will be added here.
}

3. Define Conversion Options Set up the conversion options to specify XLS as the target format:

var options = new SpreadsheetConvertOptions { Format = SpreadsheetFileType.Xls };

4. Perform the Conversion Execute the conversion and save the result:

int counter = 1;
converter.Convert((saveContext) => new FileStream(string.Format(outputFileTemplate, counter++), FileMode.Create), options);

Key Configuration Options

  • PersonalStorageLoadOptions: Tailors loading settings for Outlook files.
  • SpreadsheetConvertOptions: Configures the target format and other spreadsheet-specific settings.

Troubleshooting Tips

  • Ensure your OST file path is correct to avoid file not found errors.
  • Check that you have write permissions in the output directory.

Practical Applications

Here are some real-world scenarios where converting OST to XLS can be beneficial:

  1. Data Analysis: Extract email data for analysis using Excel’s powerful tools.
  2. Reporting: Create reports from email statistics and trends.
