Export Data to Excel

I need to have a simple spreadsheet with a column with information from visits to all my sites that updated automatically in real time.

Is that possible?

Kind of confused of what you're asking. You want to spreadsheet to update in real-time? All standard spread sheets you download from Clicky will be up to date from the second you download them.

So no, this is not possible straight out of the box from Clicky. You could use their API to access and store this data in a database or Access table then display/access it from Excel or if you're not picky put that into a JSON/XML feed.
