VKospi data – where to find individual values for calculations?

Hello all,

does someone know where I can find VKospi data as individual values, best in an excel table to download? Basically, it is the VIX data for South Korea.

So far I could only find graphs to download. But there are many research papers for which the data could be obtained. One said mentioned this source: South Korean stock exchange. However, I could not find it, maybe because I don't speak Korean.

Thank in advance for your help.
