Hi Product Hunt! I'm Armin, the maker of MindySheets. Most spreadsheet work isn't analysis. It's cleaning up exports, hunting for duplicates, fixing #REF! errors and rebuilding the same report every month. I built MindySheets so you can hand that part to Mindy, an AI spreadsheet assistant. How it works: Upload an Excel or CSV file. Mindy checks every column and flags duplicates, spelling variants, numbers stored as text, mixed date formats and broken formulas. Ask questions in plain English, like "Which region grew fastest this quarter?" Claude plans the calculation and our engine runs it over every row, so the numbers are exact, not estimates. Every answer shows how it was calculated. Approve the fixes you want, then download a clean Excel file with a list of every change, or a report with charts. Privacy mattered to me from day one. Your file is opened inside your browser and never uploaded to our server. The AI only sees a short summary and the calculated results, and Private mode holds back example rows too. It's free to try with no sign-up (25 AI credits a day), plus 8 free tools like an Excel formula generator and a duplicate finder. I'd love your honest feedback. Which spreadsheet chore would you most like Mindy to take off your plate?
