Show HN: Local Mail Merge in the Browser – No Cloud, No Setup

1 points by somtom 3 days ago

I needed to print 50+ personalized letters for my local fire fighter department. Most tools made this harder than it should be:

* Word Online (M365) doesn’t support mail merge * Google Docs never did * My old Apps Script broke

So I built a browser-based tool over the weekend:

* Upload a .docx template * Upload a .xlsx (or .csv) file with recipient data * Download a .docx with personalized letters — all locally in your browser, no cloud involved

It’s open source and privacy-friendly. Works well for quick offline letter runs or any task where email isn’t viable.

Maybe this helps folks out there with a similar problem. Would love feedback and ideas for improvement!

Handling personalized letters without cloud hassle sounds tricky. You might want to check out mailsai for cold email campaigns—it’s simple to use and keeps things local. It helped me streamline outreach without the usual setup headaches.
