Excel formulas can be frustrating. VLOOKUP, nested IFs, SUMPRODUCT, INDEX-MATCH — they're powerful but confusing. GPT-4o on 4omodel.com is your free formula translator: describe what you want in plain English, get the Excel formula.
How it works: tell GPT-4o something like 'I need a formula that looks up a product name in column A and returns the price from column C.' It responds with the exact formula: =INDEX(C:C,MATCH("Product",A:A,0)) plus an explanation of how it works.
GPT-4o doesn't just write formulas — it teaches you. Each formula comes with a breakdown of what each part does, common pitfalls to avoid, and suggestions for related functions you might find useful.
Beyond basic formulas, GPT-4o helps with pivot table strategies, conditional formatting rules, data validation setups, and VBA macros. If it's in Excel, GPT-4o can help.
Google Sheets users benefit equally — GPT-4o knows both platforms and can translate formulas between them. It also handles Google Sheets-specific functions like QUERY, IMPORTRANGE, and ARRAYFORMULA.
