Here's a problem that sounds small on the surface but reveals a much bigger gap in how most spreadsheet users think about dates. The user needs a due date that accounts for weekends when the request type is Standard, but keeps a simple calendar-day calculation when the request is Expedited. That is not a niche ask. It is the exact kind of real-world logic that spreadsheets were supposed to handle from the start, yet the default formula treats every day the same. Saturday and Sunday count the same as Monday. Holidays? Invisible. The user's current setup is honest, functional, and wrong for the workflow it supports.
The fix is straightforward, and that is the point worth pausing on. Excel 365 has the WORKDAY function built in. For the Standard row, the formula in Column I becomes `=WORKDAY(E2, 5)`. For Expedited, the user wants one calendar day, so `=E2+1` works fine. Combine them with the same IFS logic already in Column H: `=IFS(G2="Expedited", E2+1, G2="Standard", WORKDAY(E2, 5))`. That is it. No macros, no helper columns, no third-party add-ins. The function has been in Excel for decades. Yet this user, like so many others, built a calendar-day system first and only realized the gap when the due dates stopped matching reality. That pattern is not a failure of the user. It is a failure of the tool's default assumptions.
What this tells us is that most spreadsheet users are working against the grain of their own data. They learn formulas in isolation, SUM, IF, VLOOKUP, and then try to assemble them into workflows that the spreadsheet was never designed to support. The result is workarounds. People add manual weekend checks, build lookup tables for holidays, or just pad the due date by two extra days and hope for the best. The user here asked the right question at the right time: how do I make the tool match my process instead of the other way around? That shift in thinking is the entire value of moving toward smarter, more dynamic formulas.
We would argue that this is exactly the kind of moment where an AI-native approach changes the equation. The user should not have to remember that WORKDAY exists or dig through Excel's function list to find it. A system that understands context, that a "due date" for a Standard request should skip weekends, could suggest the correct formula before the user even finishes typing. That is not a distant future. It is a practical next step for anyone building spreadsheets that are meant to be used, not just filled in. The formula is the solution, but the real win is making the formula invisible. Start with WORKDAY today. Then ask yourself what else your spreadsheet assumes that your business does not.
