I built up a new Foundation Template with artificial data that roughly matches up with income streams and expenditures of a generic household. There are periodic rent and paychecks, there are roughly balanced budgets with some variability month to month, and all the data is categorized.
The three-year data set is structured to always be “current” by mapping dates to begin at the end of the current month. (So, if today is March 15th, the newest transaction will be a few weeks into the future at the end of March.)
Honestly it could be for both scenarios I have a reset function that I use to clear my sample data in the various sheets . For tiller you could add it to the tools section add sample data/ clear sample data
