How to load a .dat (comma-separated)

How can I read a file in .dat format, which has three commas in each row and only the second is a separator? The others are decimal separators.

Maybe I do not explain my problem sufficiently, so I attach the mentioned file.

v=importdata('1.dat')
w=v(1:2:end)
out=regexprep(w,'(?<=\S+,\S+),', ' ')

Thank you for your quick answer. Please, what would be different if I need to remove all the commas?

out=regexprep(w,',', '  ')
