Excel Formula AI Assistant
Describe your Excel task in plain language and get a paste-ready formula (= prefix) with explanation, steps, and alternatives. Explain or fix broken formulas (#REF!, #N/A). 12 built-in snippets (VLOOKUP, INDEX+MATCH, SUMIFS). For batch automation see /excel-vba-ai. Formula drafts stay in browser localStorage. AI uses your own API key per request—it is not stored on our servers.
