How to publish a text as Pdf or Doc?

If you just want your browser to download a distant PDF or Doc file, use the Browser plugin and its action "Invoke download".

If you mean that the data for your exercise is in PDF or doc format and you want to load them into your web app, you could load up the content of the file using the AJAX plugin.

But concerning parsing those file format into data that you can use from within Construct, there isn't standard plugin that will help you with those.

Especially since these are proprietary formats.

You should rather look into JSON format and the JSON plugin for that.

you are in luck! I have been working on integrating jsPDF into C3 over the last few days...

here is a sample project that builds a pdf:

this is the jsPDF documentation, which doesn't include many examples but helps.
