DatumInt

Datumint is an online workspace for fixing messy CSV files in one click so you don’t have to wrestle with Excel formulas or write Python scripts. Upload a messy CSV, hit Clean, and in seconds you get a tidy file back - obvious duplicates removed, empty or broken rows stripped out, and common formatting issues smoothed over, all right in your browser.

Around this one-click Clean Workspace, Datumint gives you a growing hub of small, focused tools for everyday data work. You can quickly preview big CSVs without freezing your machine, filter rows to isolate just the records you care about, extract or merge columns without touching a spreadsheet, and run quick checks before sending data to a client, CRM, or report. It’s designed for students, marketers, freelancers, and founders who keep ending up with ugly CSVs but don’t want to become “data people” just to clean them.

The idea is simple: whenever you bump into an annoying data task - from inspecting a file a client sent, to cleaning scraped leads, to fixing a project dataset the night before a deadline - there’s almost always a focused tool in the Datumint hub that lets you handle it fast, in your browser, and often in just one click.
