How to get a webpage data into an Excel instantly [on hold]

http://ift.tt/1fHYNX2 This site is releasing the economic data on a predefined time as shown.

I want the releasing data on the specific time into an Excel sheet instantly (no delay). For example, a data will be released on 9 o'clock, right after the data is released, it will be recorded into the pre-opened excel sheet instantly.

In this case, What do I have to do? I want to know a rough outline of the process. Please understand my English.
