Document conversion(xlsx,doc,ppt) to PDF from amazon s3 bicket

You can do the file conversion through use of the DocumentConverter in a back-end service, and then render the image onto your viewer. Optionally, the LEADTOOLS DocumentViewer object can also be used to render the PDF in an Angular created app. Here is some code which demonstrates the conversion and resources you can use:

using (DocumentConverter documentConverter = new DocumentConverter())
{
var input = @"C:\Inputfiles\input.xlsx");
var output = @"C:\Outputfiles\output.pdf");
var jobData = DocumentConverterJobs.CreateJobData(input, output, DocumentFormat.Pdf);
jobData.JobName = "save pdf";
var documentWriter = new DocumentWriter();
documentConverter.SetDocumentWriterInstance(documentWriter);
var renderingEngine = new AnnWinFormsRenderingEngine();
documentConverter.SetAnnRenderingEngineInstance(renderingEngine);
var job = documentConverter.Jobs.CreateJob(jobData);
documentConverter.Jobs.RunJob(job);
}
