Did the same for a while, usually to have a short-term period, then I tried gnucash (no undo) and hledger which nowadays has some features for planning ahead. But still, I decided to write my own webapp for my personal finances and long-term budgeting.
If your excel files have anything for forward planning and you want to share those files, I'd be interested.

Unfortunately there was no planning involved, one spreadsheet was just for her to put stuff she bought and the spreadsheet would calculate how much she spent in the month/week. Another one was for her to calculate how much the Saturday children center she is running would earn per month.
Since you made a webapp for personal finances, let me mention you the one a friend made: https://spendbook.net/main it doesn't do planning but I think he'll still be happy to get some feedback.
