What are /r/as400's favorite Products & Services?

From 3.5 billion Reddit comments

Depending on how deep you want to go I would recommend Microsoft PowerBI Desktop, its free. Very easy to get up and running and you can export to excel for action. https://powerbi.microsoft.com/en-us/desktop/

Also depending on how old your AS400 is getting data out of it to any other platform might be your biggest challenge.
