Not really much to show about it, I quite literally just made some normal docx and xslx files in office, unzipped them, made them into eex templates, then just render the templates back out with the data and re-zip the contents, it’s really really simple… >.>

Might be worth a blog entry sometime perhaps.

That’s my very job, so I foreign wrap the oracle horrors into postgresql for a singular interface to it (and others). ^.^;

I remember the time where I’ve once generated cards with coupon codes with by drawing such cards in Inkscape (which produces SVG files), and writing the text I needed to replace between curly brackets ({{var}}) inside Inkscape, of course. Then, I would treat the whole SVG file as a Jinja template, and simple replace the text. After that, I don’t remember if I used Inkscape to export the SVG as PDF again or if I used Qt’s SVG renderer, but the whole idea of writing an SVG template directly in Inkscape was very cool.

This one again

Honestly, this is not really an issue unless you are really hitting heavy numerics (scientific; ml; transcoding ..) and these days there are libraries with NIFs (natively compiled code) for the heavy lifting for many/most of these needs.
