Microsoft Project (.MPP) files contain detailed project schedules, resources, timelines, and dependencies. However, in order to view them, you need particular software such as MS Project Professional, MPP Viewer, Project Reader etc. However, by converting these files to HTML makes project plans accessible through any browser, ideal for online sharing, embedding, or documentation.

In this guide, you’ll learn how to convert MPP to HTML using .NET Cloud SDK, including steps to upload files from your local machine, convert MPP files already in cloud storage, and download the resulting HTML file.

Why Export MPP to HTML?

Converting Microsoft Project to HTML provides multiple benefits:

  • Universal Access: View project plans in any browser without MS Project.
  • Easy Sharing: Embed HTML in wikis, websites, or internal dashboards.
  • Lightweight Format: HTML is portable and ideal for online documentation.
  • Cross-Platform: Works on Windows, macOS, Linux, and mobile devices.

Convert MPP to HTML — C# Example

Below is a complete C# example demonstrating details on how to:

✔ Initialize the API
✔ Upload an MPP file to cloud storage
✔ Convert it to HTML
✔ Download the resulting file

Step 1 - Create TasksApi object:

var tasksApi = new TasksApi(clientSecret, clientId);

Step 2 - Upload MPP to Cloud storage:

using (var fs = File.OpenRead(localMPPFile))
{
    var uploadRequest = new PostCreateRequest(remoteName, fs);
    tasksApi.UploadFile(uploadRequest);
}

Step 3 - MPP to HTML conversion options:

var formatRequest = new GetTaskDocumentWithFormatRequest()
{
    Name = remoteName,
    Format = ProjectFileFormat.Html,
    ReturnAsZipArchive = false
};

Step 4 - Initiate MPP to HTML Conversion:

var result = tasksApi.GetTaskDocumentWithFormat(formatRequest);

✅ Tip: If you already have the MPP in cloud storage, skip the upload step and set a Name to the remote path of the MPP file.

Export MPP to Excel via cURL (REST)

Another approach is the usage of cURL commands, as they further streamline the conversion process. It allows you to seamlessly integrate this feature into your applications or workflows. This approach also empowers you to automate the MPP to XML conversion, making it a practical choice for those looking to handle large volumes of project data efficiently.

Step 1 - Get an access token:

curl -X POST "https://api.aspose.cloud/connect/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -H "Accept: application/json" \
  -d "grant_type=client_credentials&client_id=YOUR_APP_SID&client_secret=YOUR_APP_KEY"

Step 2 - Convert MPP to HTML

curl -v -X GET "https://api.aspose.cloud/v3.0/tasks/{sourceMPP}/format?format=html&returnAsZipArchive=false" \
-H  "accept: multipart/form-data" \
-H  "authorization: Bearer <JWT Token>" \
-o  project_output.html

Replace {sourceMPP} with the MPP file name or path in cloud storage.
