I have spent the last few weeks in my spare time giving ChatGPT a spin for developing browser-based engineering software modules accessed in the xl4sim.com website. It covers many topics including statics, shock, steady and random vibration, water- and air-cooled heat sinks, black rubber processing and mechanics, and other.

This blog shows how MS Excel and Google Sheets can be used for engineering and other technical applications. Examples of their use will be given and discussed. They will be in the form of COM Add-ins, macros, templates, user functions, Google scripts, simple forms, online calculators and other. Disc…
