Web App (Chrome) hangs in loading CSV dataset with 10000 columns

I am starting to experiment, and I just loaded a CSV file with 1000 rows and 10001 columns.
All columns are numeric except for the last one which is categorical.

However, as mentioned in the title of the topic, the web app running via Chrome hangs, and the pesky ‘unresponsive dialog’ is always showing.

Any alternatives on how to load this CSV?
And also how to set the output port without scrolling to all the columns once the data is loaded?

Thanks!

Sorry for making a very quick follow but any Ideas/help here?
Thanks!

Hi DLS supports only 1000 columns.
