Hey Product Hunt! 👋 I'm the maker behind Randify. Really excited to share this with you! **Why I built it:** I needed to anonymize sensitive data for testing. Every tool I found required uploading data to someone's server. That felt wrong, especially when working with confidential company information. **What makes it different:** Randify runs 100% in your browser. Your data never leaves your device - not because I promise, but because it's technically impossible. **How it works:** 1. Paste table data (e.g., from Excel) 2. Select columns to anonymize 3. It randomizes while preserving format: - Emails become realistic fake emails - Phone numbers keep their format - Dates stay as dates - Names become realistic fake names **Perfect for:** - HIPAA-compliant work - Creating test data - GDPR compliance - Sharing data structure safely **Tech:** Vanilla JS + Browser APIs. No backend. $0/month to run. **What's next:** JSON support, more formats, custom rules. I'd love your feedback! What features would make this more useful? Thanks for checking it out! 🚀 P.S. Also built PDFMerge, ImageResize, PasswordGen - all client-side: https://zerodatalabs.io
