    The easiest way would be to spell out exactly what you want replaced:

    Replace

    ^(\S+)\s+(\S+\s+\S+)\s+(\S+)\s+(\S+)\s+

    by

    \1,\2,\3,\4

    This is easiest because you’re complicating things by needing to include knowledge how the fields look like, e.g. the second column includes a space that should not be replaced.
