Implementation Guide

Let’s walk through the process of converting OST to XLSX step-by-step.

Load an OST File

Overview

Loading an OST file is crucial as it prepares your data for conversion. GroupDocs.Conversion provides specific load options tailored for OST files, which can be configured based on your needs.

Step 1: Define the Source File Path Start by specifying the location of your OST file:

string sourceFilePath = @"YOUR_DOCUMENT_DIRECTORY\sample.ost";

Step 2: Set Load Options Use PersonalStorageLoadOptions to ensure proper handling of OST files:

var loadOptions = new PersonalStorageLoadOptions();
using (var converter = new Converter(sourceFilePath, () => 
    sourceFilePath.EndsWith(".ost") ? loadOptions : null)) {
    // Conversion logic can be added here
}

Explanation: The loadOptions parameter is used to configure how the OST file should be loaded. It ensures that any specific characteristics of OST files are appropriately handled.

Convert OST to XLSX

Overview

This feature enables you to convert an OST file into a more accessible and widely-used format, XLSX.

Step 1: Define Output Paths Set up your output directory and filename pattern:

string outputFolder = @"YOUR_OUTPUT_DIRECTORY";
string outputFilePattern = Path.Combine(outputFolder, "ost-converted-{0}-to.xlsx");

Step 2: Configure Conversion Options Choose the conversion options suitable for spreadsheet formats:

var conversionOptions = new SpreadsheetConvertOptions();
int counter = 1;
using (var converter = new Converter(sourceFilePath)) {
    // Convert and save the file in XLSX format
    converter.Convert(
        (saveContext) => new FileStream(string.Format(outputFilePattern, counter++), FileMode.Create),
        conversionOptions
    );
}

Explanation: The SpreadsheetConvertOptions class allows you to specify various options for converting data into spreadsheet formats. It handles the intricacies of formatting and ensures compatibility with Excel.

Troubleshooting Tips

  • Ensure Correct File Paths: Verify that your source file path is correct to avoid loading errors.
  • Check Dependencies: Make sure all necessary packages are installed and updated.
