Describe needs in natural language, AI generates runnable Excel formulas and VBA macros

Problem: Many office workers are unfamiliar with Excel formulas or VBA, spending hours searching or trial-and-error. A developer built FormulaAI with VBA generation and anonymous use, showing strong demand for natural-language-to-spreadsheet-code.
Solution: A web tool where users upload a spreadsheet or paste headers, describe desired calculations or automation in natural language (e.g., 'add a button to sum all department sales'), and AI generates copy-paste-ready formulas or VBA code with comments.
Users: Operations, finance, admin staff handling Excel, and non-VBA office workers wanting to automate repetitive tasks.
MVP: Upload CSV/XLSX and read headers; input natural language description; call LLM to generate Excel formula or VBA code; display result with one-click copy; anonymous use with daily limit.
Revenue: Free 5 times/day; $9/month for unlimited and advanced models; or $49 one-time desktop license.
Why now: LLMs are reliable enough for code generation, and office formula/VBA needs are massive and long-tail; indie devs can build fast and acquire via SEO.
