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:

Just shipped some exciting updates to Randify based on user feedback:
🎯 Enhanced Number Detection - Finally fixed that annoying Excel issue where numbers get stored as text! Now handles apostrophes, quotes, currency symbols, and all those invisible characters Excel loves to add.
🎨 Manual Type Override - Not happy with how we detected a column? Just click the type badge and pick what you want from a dropdown. Super simple.
🔀 Shuffle Mode - This one's my favorite! Instead of generating completely new values, you can now shuffle your existing data. Perfect when you want to keep the "feel" of your real data but just mix it up. Click the 🔀 button on any column.
🤝 Preserve Relationships + Shuffle Together - You can now use both features at once! Shuffle keeps duplicates together, so if "John" appears 3 times, all 3 become the same shuffled value. Game changer for maintaining data relationships.
Still 100% private, still runs in your browser, still free. Would love to hear what you think! 🚀
