NuGet Package Manager Console:

Install-Package GroupDocs.Conversion -Version 25.3.0

.NET CLI:

dotnet add package GroupDocs.Conversion --version 25.3.0

Implementation Guide

This section walks you through loading an MBOX file and converting it into CSV format. We’ll break it down by feature for clarity.

Feature 1: Load MBOX File

Overview

Loading an MBOX file is the first step in our conversion process. GroupDocs.Conversion provides a straightforward way to handle this using MboxLoadOptions.

Implementation Steps

Step 1: Define your MBOX file path and load options:

string mboxFilePath = @"YOUR_DOCUMENT_DIRECTORY\\sample.mbox";
MboxLoadOptions loadOptions = new MboxLoadOptions();

Step 2: Create a Converter instance to handle the conversion process:

var converter = new Converter(mboxFilePath, (LoadContext context) => {
    return context.SourceFormat == EmailFileType.Mbox ? loadOptions : null;
});

Why this step? This ensures that only MBOX files are processed with the specified options.

Feature 2: Convert MBOX to CSV

Overview

Once the MBOX file is loaded, we can convert it into a CSV format. The conversion process utilizes SpreadsheetConvertOptions.

Implementation Steps

Step 1: Set up your output directory and template:

string outputFolder = @"YOUR_OUTPUT_DIRECTORY";
string outputFileTemplate = Path.Combine(outputFolder, "mbox-converted-{0}-to.csv");

Step 2: Define conversion options for CSV format:

SpreadsheetConvertOptions options = new SpreadsheetConvertOptions { Format = SpreadsheetFileType.Csv };
int counter = 1;

Step 3: Execute the conversion and save each file as a CSV:

counter = 1; // Reset for clarity in explanation
converter.Convert(
    (SaveContext saveContext) => new FileStream(string.Format(outputFileTemplate, counter++), FileMode.Create),
    options
);

Why this step? This handles the actual conversion and ensures each email is saved in a new CSV file.

Troubleshooting Tips

  • Ensure your MBOX path is correct; otherwise, you’ll encounter file not found errors.
  • Verify that GroupDocs.Conversion is properly installed and referenced in your project.

Practical Applications

Here are some real-world scenarios where converting MBOX to CSV can be beneficial:

  1. Data Analysis: Exporting email data for analysis using spreadsheet software like Excel.
  2. Email Archiving: Preserving emails in a more universally readable format.
  3. Integration with CRM Systems: Importing email data into customer relationship management platforms.
