For 9.99 introductory price I think is awesome. 3 questions: 1. With the Lua script, can I call a web service or a web page to get an xml or or a json with data and load that response directly to a sheet? 2. How do I put a button or something to trigger a script? 3. Can I open one of your files from a web link? as in "Open in..." With those 3 items I have a server controlled reporting app.
