Is it possible to track updating information on a webbpage and then take action (manipulating the web page)based on that information in conjunction with data that is in a libre calc document?
One can say that there are two variables. One is on the webb page and the other on is in a libre calc document. The program has to keep track of both and then take action once the right conditions are fulfilled.
Libre calc could run in an other tab in the webbrowser.
or on the computer depending on whats is easiest or and the most functional way.
