CSVtoSheets is a tiny Mac app that turns the most annoying part of working with data into a double-click. Every time you export a CSV from a BI tool, ad platform, or bank, opening it in Google Sheets means the same routine: new sheet, File, Import, upload, pick settings, wait. Three minutes of clicking you repeat hundreds of times a year. CSVtoSheets kills that. Double-click any .csv, .xls, or .xlsx file and it opens as a fresh Google Sheet in about a second. Setup takes roughly 30 seconds. You sign in with Google once, in your browser, and the app handles every file from then on. No import dialog, no manual upload, no copy-paste. It's built for people who live in spreadsheets — analysts opening daily BI exports, marketers turning ad-platform dumps into shareable dashboards, finance and ops teams cleaning up payout and expense reports. If you open more than a couple of CSVs a week, it pays for itself in days.
