I noticed people manually copy-pasting data from Excel into PDF forms, but existing solutions require uploading sensitive data (employee info, invoices) to third-party cloud servers.
I built FormFill to do all the heavy lifting entirely in the browser using pdf-lib. It parses the Excel file, maps the columns to your created PDF fields, and generates a .zip of filled PDFs locally.
Because it's 100% client-side:
1. User data never leaves their device.
2. Server computing costs are essentially $0.
You get a few free batch exports just by visiting (no sign-up required). I'd love to hear your feedback on the mapping UI and the pure frontend approach!
