Can't really do it without a 3rd party DLL or service. Some of the newer marketplace addons use the Free Spire.Doc .NET library, which is pretty easy to work with and would be easy to implement. There is a paid version of Spire.Doc, but the free version would likely suffice for most purposes (and can be used for commercial purposes)

Ryan Farley,

thank you for your response and for the recommendation,

I actually downloaded the free version of Spire.Doc and started exploring it — it does look quite promising. However, since I’m working entirely within Creatio Cloud, I believe there might be a limitation when it comes to using third-party DLLs directly, though I’m not completely sure.

Do you think it would be viable to integrate Spire.Doc by hosting the functionality externally (for example, as a microservice or an Azure Function) and calling it from Creatio via a REST API? I’d love to hear your thoughts on whether that approach makes sense or if you’ve seen it work in similar cases.

Thanks again for your help and insights.

Paulo Chacoff Leiton,

As Ryan said, we use the paid version of Spire.Doc in our marketplace app: https://marketplace.creatio.com/app/experceo-word-pdf-converter-creatio

It allows you to generate an unlimited number of PDF documents with unlimited pages (the Free version is limited to 3 pages).

Thank you
Mohamed
 

Still amazes me how conversion to pdf is not an Out of the Box feature of Creatio

(actually was and disappeared a couple of years ago)

We have used aspose connector in the past but there are a lot of errors in communication and quality is not acceptable.
we are also considering using the Spire.Doc library for future developments

Ryan Farley,

Do you happen to have a reference of how to invoke functionality from external libraries or assembly reference? i´ve trying to use Spire.doc in a source code file and script task but i always get a "missing assembly reference"

Just to illustrate the attempt, here´s a basic example a tried to convert word document to PDF with source code file:

Any guidance on how to properly reference and use third party libraries like this in Creatio would be appreciated.

using Spire.Doc;
using Spire.Doc.Documents;
using System.IO;
 
namespace JJ
{
    public class DocService
    {
        public byte[] GenerateDocx() {
            var doc = new Document();
            doc.AddSection().AddParagraph().AppendText("Hola desde Creatio!");
            using (var ms = new MemoryStream()) {
                doc.SaveToStream(ms, FileFormat.Docx);
                return ms.ToArray();
            }
        }
        public byte[] ConvertToPdf(byte[] docxBytes) {
            var document = new Document();
            using (var ms = new MemoryStream(docxBytes)) {
                 document.LoadFromStream(ms, FileFormat.Docx);
            }
            using (var outMs = new MemoryStream()) {
                 document.SaveToStream(outMs, FileFormat.PDF);
                 return outMs.ToArray();
            }
        }
    }
}

Fixed the issue by manually installing Aspose Word dll. I haven't noticed issue happening in 7.17.3
