Building a Neural Network in Microsoft Excel: The Ultimate Proof of Concept

We all know the mantra: "You need a GPU, a cloud instance, or at least a Jupyter notebook to train a neural network."

ChatGPT for Excel: A new add-in from OpenAI allows you to run complex models and "agent" scenarios directly within cells.

Pro Tips: Optimizing Your New Excel Neural Network

1. Use the LET Function for Performance

Instead of repeating calculations, use LET to store intermediate matrices. This is the modern Excel equivalent of object-oriented programming. build neural network with ms excel new

Copy S1 down to S4.

Copilot "Agent Mode": As of late 2025, Microsoft Copilot's Agent Mode can generate the structure of a predictive model or neural network by simply describing the task in plain English. 2. Step-by-Step Build (Traditional Formula Approach) Building a Neural Network in Microsoft Excel: The

Conclusion: Why This Changes the Game

Building a neural network with MS Excel using the new functions (RANDARRAY, MMULT, LAMBDA, spill ranges) democratizes deep learning.

• Input Layer: two cells for X1 and X2
• Hidden Layer: two cells for the hidden neurons (H1 and H2)
• Output Layer: one cell for the output (Y)

A standard neural network consists of three main components you’ll need to map out in your sheets: Input Layer: Your raw data (e.g., petal length, width). Input Layer: two cells for X1 and X2

Calculate the Weighted Sum: Use the SUMPRODUCT function to multiply inputs by their weights and add the bias.
