Sheets Formula Explainer

Sheets Formula Explainer uses AI to decode any Google Sheets formula in seconds. Paste a complex VLOOKUP, ARRAYFORMULA, or QUERY and get a clear, plain-English explanation instantly. Need a new formula? Describe what you want in everyday language and the AI generates it for you.

🎯 Why This Extension Exists

Spreadsheet formulas can feel like a foreign language. A single formula combining INDEX, MATCH, IF, and IFERROR can span multiple lines and take hours to decode manually. Most people either give up, search for answers in a new tab, or avoid complex formulas altogether—leaving the real power of their spreadsheets untapped.

This extension puts an AI formula expert directly inside your browser. No copy-pasting into ChatGPT, no context switching, no guesswork. Click the icon, paste the formula, and understand it within seconds. It also works in reverse: describe what you need and get a working formula back.

🚀 How It Works

Two powerful modes in one lightweight popup:

▸ Explain Mode — Paste any spreadsheet formula and click Explain. The AI breaks down every function, argument, and nested operation into a step-by-step walkthrough. Even deeply nested formulas with five or six layers are explained clearly.

▸ Generate Mode — Type a description like "sum column B where column A equals January" and get the exact formula you need. No syntax memorization required.

▸ History Panel — Review previous explanations and generated formulas without re-entering them. Useful when working across multiple sheets.
