From rigid rows to flexible forms: how AI helps calculate any shape.

Calculating volumes for irregular shapes in Excel is indeed possible, and your idea of using a graph to represent dimensions is a creative approach.

We are going to say what every spreadsheet user has felt but never articulated: you should not have to reshape your problem to fit a grid of rigid rows and columns. A Reddit user recently asked if it was possible to calculate the volume of a custom form in Excel using a graph and a depth field. They apologized for their English and called it a "dumb question." It was neither. That instinct, to draw the shape, annotate the depth, and let the tool do the rest, is a vision of how spreadsheets *should* work. The fact that Excel made them doubt themselves is the real problem.

Traditional spreadsheets treat every calculation as a rectangular arrangement of cells. You want to calculate the volume of an irregular form, so you flatten it into a table, then lean on formulas that feel like workarounds. The user's idea, create a graph, define a depth, let the software reason about the geometry, is not a bad method. It is a smarter, more human method. Graph-based calculation is how our brains approach shapes. You see a form, you visualize its dimensions, and you ask for an answer. The disconnect is that legacy tools force you to translate that mental model into a grid before they will talk to you. That translation step is where productivity dies.

Now, AI-native spreadsheet technology changes that equation. Instead of forcing your problem into the tool's shape, the tool adapts to your problem. You describe the form in natural terms: "here is a graph of the outline, and here is the depth." The AI interprets the geometry, performs the calculation, and returns the result. No cell references. No formula debugging. No apology required. The user who posted that question already understood the core principle: the interface should match the way you think, not the way the software was architected in 1985. They just needed permission to expect better.

So our opinion is direct: the future of data management belongs to tools that treat your question as a valid starting point, not a failure of understanding. If your spreadsheet cannot handle a simple volume calculation from a drawing, it is the spreadsheet that is limited, not you. We encourage you to stop adapting to outdated constraints and start exploring the alternatives that reason the way you do. The next time you have an idea that feels too organic for a grid, trust it. Then find the tool that meets you there.

My idea was to maybe create a Graph 📈 and then you can Write the depth of the Form somewhere and it somehow calculates it.

Sorry for my Bad Englisch and my probably dumb question.
