Convert OneNote to Zettlr Markdown

Code Example: OneNote to Zettlr Markdown

Here’s a practical C# example that demonstrates the entire conversion process:

    using Aspose.Html;
    using Aspose.Html.Converters;
    using Aspose.Note;
    using System.IO;

    public void ConvertOneNoteToZettlr()
    {
        string oneFilePath = "path/to/your/onenote-file.one"; // Path to OneNote file
        string mdFilePath = "path/to/output-file.md";         // Output markdown file for Zettlr

        using (var ms = new MemoryStream())
        {
            // Step 1: Load the OneNote document and save it as HTML
            Document document = new Document(oneFilePath);
            document.Save(ms, SaveFormat.Html);
            ms.Position = 0;

            // Step 2: Load the HTML from memory stream and convert it to Markdown
            HTMLDocument htmlDocument = new HTMLDocument(ms, "temp.html");
            MarkdownSaveOptions options = new MarkdownSaveOptions();
            Converter.ConvertHTML(htmlDocument, options, mdFilePath);
        }
    }

Follow these steps to convert OneNote files to Zettlr-compatible Markdown using C#:
1. Export OneNote to HTML: Use Aspose.Note for .NET to extract the content of your .one file and save it as HTML.
2. Convert HTML to Markdown: Use Aspose.Html for .NET to transform the HTML file into Markdown format, retaining the structure and formatting required for Zettlr.

This code snippet shows how to seamlessly convert a OneNote (.one) file into a Markdown (.md) file optimized for Zettlr. The first step leverages Aspose.Note for .NET to load the OneNote file and save it as HTML in memory. The second step uses Aspose.Html for .NET to process the HTML content and convert it to Markdown format, ensuring the integrity of your notes. This efficient approach guarantees high-quality results, making it easy to transition your notes into Zettlr’s markdown-based environment.
