DataMatch - Visual data reconciliation made incredibly simple

Hey Product Hunt! 👋 I’m thrilled to introduce DataMatch today! Let’s be honest: comparing massive CSVs and Excel files manually is soul-crushing work. Whether it’s finding a missing payment in an accounting ledger, or trying to figure out why two system exports don't match, writing complex Python scripts or VLOOKUPs is time-consuming and error-prone. I built DataMatch to fix this. It’s a next-generation data integrity platform that replaces endless spreadsheets with a beautiful, intuitive node-based canvas. ✨ How it works: Drag & Drop: Pull your data sources right onto the canvas. Connect: Link them to the Match Engine. Map: Set your primary keys and rules (e.g., exact match, numeric tolerance). Solve: Instantly see exactly what matches, what’s mismatched, and what’s entirely missing.
