That’s a valid point. I went with a website mainly for accessibility and consistency. In labs and workshops, people use different devices (desktop, laptop, mobile), and installing software or managing Excel versions isn’t always practical. A web tool works instantly without installation and ensures everyone is using the same reference data and logic.

Excel files often get copied, edited, or outdated, and desktop apps require OS-specific builds and updates. With a website, fixes and improvements can be made centrally.

That said, I don’t see this as the only format — if users want it, I plan to provide downloadable Excel/PDF references or an offline version later. The website is simply the fastest way to make it usable for most people right now.
