Correlation figures between world indices?

Where can I free correlation data for 4 main U.S indices Dax,Ftse,Cac,Spi,Hsi,Nikkei,etc? besides website that requires subscription fees such as CSiData.com...
 
Thanks, how do you import data day to day automatically into excel so I don't have to download the whole chunk of data everyday?

What about intraday correlation?
