Someone else said this on HN but I’ll say it here; this is great not only because it shows how powerful the scripting can be in google sheets, but also because it’s such a clear distillation of how computers work.
Cool project, only downside is how dog slow Apps Script seems to be. I tried it once for another project and was amazed at how long it took to do a few trivial UI manipulations. This seems to be about as not fast. I gotta wonder how it manages to be so slow, and if they’re planning on improving it any.
Say what you will about VBA, it’s at least pretty fast. App Script IMO needs to be more competitive to get more people moving from MS Office.
