Recently I had to convert my budgeting spreadsheet from Excel to Google Sheets. While I was doing that, I also made a blank version to share as a template, in case anybody else might like to use it!
It works a little differently than most budget spreadsheet templates I've seen. With this, you keep a running list of your transactions, and you assign them to different Funds, which are like folders in your checking account (or savings, or wherever). The spreadsheet has formulas that keep running totals for your accounts and funds, so you can see how much money you have left for each purpose!
I've also made a Sample sheet, which has some imaginary entries, as well as comments to explain how things work.
