The easiest I can think of is making a spreadsheet. Share an Excel file over OneDrive or even a Google Sheet. The built-in features/formulas are enough for most of these use cases; if you want to go further, there's VBA (and the nightmare that comes with it - but it's less of a nightmare than paying and setting up a domain and dealing with the security of that). I know several people who do that - non-programmers - with formulas and VBA in Excel sheets.
