This Reddit user's question captures a frustration that nearly every spreadsheet user has encountered: the moment VLOOKUP fails you. It's not a failure of effort, it's a failure of the tool. The user has a clean table, a clear goal, and a reasonable expectation: sum the stock for "Apple" across two rows. VLOOKUP, by design, returns the first match and stops. That's not a bug; it's a limitation baked into a formula built for a world without AI. And the workarounds, array formulas, helper columns, pivot tables, are exactly the kind of complexity that makes people feel like they're the problem.

We think this moment is exactly where AI-native spreadsheets earn their place. The user shouldn't have to know about SUMIFS or INDEX-MATCH to get a simple answer. They shouldn't need to restructure their data or learn a second formula language. What they need is a tool that understands intent: "I want the stock of Apple, summed across all matching rows." That's a natural question, not a technical one. And in an AI-native spreadsheet, it's a question the tool can answer directly, no formula writing required.

What this means in practical terms is a shift in how you interact with data. Instead of memorizing function syntax or debugging nested formulas, you describe what you want. The AI handles the aggregation, the lookup logic, and the return of the correct value. The user in this post spent time crafting a VLOOKUP, hitting its limit, and then turning to a forum for help. An AI-native tool would have simply asked: "Do you want the sum for all matching entries?" and delivered the answer in one step. That's not a minor convenience. It's a fundamental change in who does the heavy lifting.

The concrete takeaway is this: if you're still writing workarounds for problems VLOOKUP can't solve, you're spending time on tasks that should be invisible. The next generation of spreadsheets isn't about learning more formulas, it's about asking better questions. This user's problem is solved instantly when the tool understands the query, not the formula. That's the standard we should expect, and it's available now.

In sheet 2, I want to get the stock of "Apple". How am I supposed to write the vlookup formula so it will get me the sum of both apples? When I try with usual vlookup formula, it only gave me the first apple "300"
