How to load and render AWS S3 files using Group Docs in .Net(Framework 4.8)

You can use AWSSDK package to load a file from S3 with GetObject method. The code snippet can be found in Load document from Amazon S3 Storage documentation article. Here is the code:

string key = "sample.docx";
Stream stream = DownloadFile(key);

using (Viewer viewer = new Viewer(stream))
{
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();                
    viewer.View(viewOptions);
}

static Stream DownloadFile(string key)
{
    AmazonS3Client client = new AmazonS3Client();
    string bucketName = "my-bucket";
    GetObjectRequest request = new GetObjectRequest
    {
        Key = key,
        BucketName = bucketName
    };
    using (GetObjectResponse response = client.GetObject(request))
    {
        MemoryStream stream = new MemoryStream();
        response.ResponseStream.CopyTo(stream);
        stream.Position = 0;
        return stream;
    }
}

Please let us know if you have any issues with rendering files from S3.

According to GetObject’s method description you should have read access rights to retrieve an object:

You must have READ access to the object.
