Implementation Guide

Loading the Source OneNote File

First, load your .one file using C#:

Step 1: Define Document Paths

Replace "YOUR_DOCUMENT_DIRECTORY" and "YOUR_OUTPUT_DIRECTORY" with your actual directory paths.

string yourDocumentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string sampleOneFilePath = Path.Combine(yourDocumentDirectory, "sample.one");

Step 2: Initialize the Converter

Load the .one file using GroupDocs.Conversion:

using (var converter = new Converter(sampleOneFilePath))
{
    // Conversion logic will go here
}

Converting OneNote to HTML

With your OneNote file loaded, proceed with converting it to HTML.

Step 3: Configure WebConvertOptions

Specify the conversion options for HTML output:

var options = new WebConvertOptions();

Step 4: Define Output Path and Convert

Ensure your output directory exists, then save the converted file:

string yourOutputDirectory = "YOUR_OUTPUT_DIRECTORY";
if (!Directory.Exists(yourOutputDirectory))
{
    Directory.CreateDirectory(yourOutputDirectory);
}
string outputFile = Path.Combine(yourOutputDirectory, "one-converted-to.html");

// Perform conversion
converter.Convert(outputFile, options);
