Convert Markdown to HTML in Java

To convert Markdown to HTML in Java, pass the source Markdown path and output HTML path to Converter.convertMarkdown(). You can also use an overload that returns an HTMLDocument when the HTML must be processed or converted further.

Markdown provides a readable plain-text syntax for headings, lists, links, emphasis, and other document structures. Converting Markdown to HTML makes that content suitable for web publishing and provides the intermediate document used by Aspose.HTML for Java to convert Markdown to PDF, XPS, DOCX, and image formats.

Convert a Markdown File to HTML

The convertMarkdown(sourcePath, outputPath) method converts an existing Markdown file directly to an HTML file:

1. Prepare the source Markdown file.
2. Define the output HTML file path.
3. Call Converter.convertMarkdown(sourcePath, outputPath) to convert Markdown to HTML.

The example converts nature.md and saves the result as nature-output.html.

// Convert Markdown to HTML using Java

// Convert Markdown to HTML
Converter.convertMarkdown("nature.md", "nature-output.html");

Create Markdown in Java and Convert It to HTML

You can generate Markdown content in your application, write it to a source file, and convert that file to HTML:

1. Create the Markdown content as a Java string.
2. Write the content to a Markdown file.
3. Pass the source and output paths to Converter.convertMarkdown().

The following example writes a heading and link to document.md, then converts the file to document-output.html.

// Convert Markdown to HTML in Java

// Prepare a simple Markdown example
String code = "### Hello, World! \n" +
        "[visit applications](https://products.aspose.app/html/family)";

// Create a Markdown file
FileHelper.writeAllText("document.md", code);

// Convert Markdown to HTML
Converter.convertMarkdown("document.md", "document-output.html");
