simple-excel VS data-importer

The Simple Excel package uses the box/spout package under the hood. In the readme it states that you can get to the underlying writer using ->getWriter().

Now we are ready to make use of the Simple Excel package from Spatie to convert our array into an Excel file.

RTFM https://docs.firefly-iii.org/data-importer/

theres some third parties that give you an API directly I believe. Firefly III lists salt edge and nordigen.

Firefly III is missing plenty of features (see below). I started Firefly III with a single user (me) and everything else is a bonus.

I will admit that I caved under pressure and built the Firefly III Data Importer:

https://github.com/firefly-iii/data-importer

It can connect to your bank via Salt Edge if it is supported. Here is the documentation on the data importer - https://docs.firefly-iii.org/data-importer/

for auto-sync you need https://docs.firefly-iii.org/data-importer with API from Salt Edge or Nordingen.

You can easily import data into Firefly III using their data importer[0] and Nordigen API or Spectre (usage is explained in [0]). Doing so automatically is just a matter of running a cron job
