Hey everyone! 👋 I'm Cris, the maker of SplitName. I built this because I kept running into the same frustrating problem at work: a spreadsheet with thousands of full names that needed to become separate first_name + last_name columns. Excel formulas and Flash Fill get you 80% of the way there. But then you hit names like: "María de la Cruz García López" (is "de la Cruz" part of the first name or last name?) "Dr. James O'Brien Jr." (prefix + suffix + apostrophe) "Carlos Andrés San Martín Sepúlveda" (compound first name + compound surname) ...and everything breaks. SplitName solves this with a hybrid approach: simple names (like "John Smith") are parsed instantly in your browser — your data never leaves your machine. Complex names get sent to AI for accurate splitting. It's completely free right now (up to 500 rows), no signup required, and supports English and Spanish naming conventions. I'd love your feedback, especially: Does it handle names from your country/culture correctly? What file formats or integrations would you want next? (API and Google Sheets add-on are on the roadmap) Try it at splitname.com — just upload a CSV or Excel file and see the results in seconds.
