Merge and export Excel Word PDF to PDF

Question

I have a lot of paperwork (document types vary between Word, Excel, and PDF). The ideal situation would be to discover a library that can combine all documents and export them as PDFs. I've looked through three libraries, but none of them seem to support all document types:

• ABCPDF
• iTextSharp

I don't wish to mix and match libraries for PDF conversion.

However - I don't mind using one library for conversion, and a separate one for merge/export.

I saw some other posts discussing word -> PDF, and Spire was mentioned.

Question: Does one of my findings actually support all of this, or can someone recommend something better? Needs to be .NET supported

Answer 1

Use GroupDocs.Merger for .NET API to merge Word, Excel, Presentation, and PDF files. 

Example:

using (Merger merger = new Merger(@"c:\document1.pdf"))
{
    merger.Join(@"c:\document2.doc");
    merger.Join(@"c:\document3.ppt");
    merger.Join(@"c:\document4.xls");
    merger.Save(@"c:\merged.pdf");
}
