I need advice about a technical problem regarding to document generation (PDF, Doc). I want to provide external data and combine that with a predefined template. The goal is to generate a lot of different kind of documents (invoices, information pages, etc..)
Is there a solution that already exists? That works with a flexible template format and can be easily combined with external data like Json/XML. The language does not really matter as long it can be uses in a Saas environment.
