I wonder about the JS#/vendor lock in responses here in HN. We're talking about a macro language in MS Office, where your development and runtime environment is very well known (MS Office). I don't know how much portability demands you expect from code you're writing to format your Excel cells. function mergeAndHideGridlines() { getRange("H15:I16").merge(); activeWindow.displayGridlines = false; } Sure I can picture someone pasting in code from his/her JS library to reuse in a macro, but I don't foresee people commonly doing the other way and having issues because the Excel function that they worked on for several days doesn't work for webpages.
