Most Excel cleaners make you pick columns and hope. DataSort reads a file the way a person would: it finds the real header row buried under junk, fixes mixed date formats, normalizes casing, and catches fuzzy duplicates. Ask for changes in plain English. Open a file from Google Drive and save your changes back, or send a sheet to Notion as a real database. Your file is parsed in the browser, only the cells the AI needs reach the model, and nothing is stored. Free tier, no signup.
