Impossible in Excel?

am never face any problem.

Mainly there is no impossible, but let us say that if you have a data that you need to run a macro on it, and you cannot set a timer in the VBA, because it keep the macro in a loop and cause Excel to Not Respond state, so either you had to set alarm for your self to manually run the macro or by trigger the macro with an action(still a manual process) or you can add a web data connection that could refresh every interval of time, and with the change of the web data values it should trigger the macro to run and do the job sound impossible?

normally il never yet experienced any problem situation in excell since i am using it as data analysis tools to help me rack and visualize data for greater insight.

Yes i faced some situations like removing hyperlinks from multi cells by ActiveSheet formula,,removing blank rows by pressing F5 ,, Concatenate and substitute with the help of google ...
i was very glad that day :)
