MailMergeDocs

Free. Runs in your browser.

You have a Word letter, certificate, or invoice and a spreadsheet of names. You want one finished PDF per row without pasting for an hour. This uses the Word already on your PC to do it, no add-in, no cloud doc service.

Why I ask: I might reach out with a question about how to improve this tool, or to mention other cool tools I build. I will never give your email address to anyone else. You only have to do this once per browser.
