    Leave empty lines before and after the data above

    Select entire data with mouse

    Hit ctrl-o or the small C in the command bar

    Anyway to load stuff like this you can use loadTable

    see reference Table etc.

    Then you can access each column

    You can name the columns when you insert one line above in the textfile like

    xvalue,yvalue,zvalue..... etc. matching the data below

    You could then use those names in your code

    For loop over the table and copy in array

    Maybe use PVector as type for array (see reference)
