I'm using a 20 KiB awk script that I wrote from scratch to calculate taxes owed from investments. German tax code is a bit tricky when your broker is abroad because you have to calculate everything yourself. Hilariously some German brokers don't even apply the FIFO rule correctly. Nevermind regulations about fees or double taxation treaties. FX rates for conversion into EUR are extracted either using rga from Swissquote's own PDFs, or downloaded off the internet. The transaction history itself is one big CSV export from their web site that is also parsed and analyzed using awk. For tax time I call the script with the year I want and transfer everything into official forms. Without spending 3 days in Excel. Or 10. I can't praise awk enough.
