Array column separations for beginners

[katarin.bern at gmail.com]

Hi,
1. I would like to ask how can I adjust array.csv like this: 
,,,-00.000146400000,   0.08000,
,,,-00.000146200000,   0.00000,
,,,-00.000146000000,   0.00000,
,,,-00.000145800000,   0.00000,

so I can have in first column -00.000146400000 and in second column 0.08000? (thanks, I am begginer).

2. How can I pick out information(number) from 20 separate files to one file? (thanks!)
