reformat in vim for a nice column layout

Question

I have this dataset in a csv file

1.33570301776, 3.61194e-06, 7.24503e-06, -9.91572e-06, 1.25098e-05, 0.0102828, 0.010352, 0.0102677, 0.0103789, 0.00161604, 0.00167978, 0.00159998, 0.00182596, 0.0019804, 0.0133687, 0.010329, 0.00163437, 0.00191202, 0.0134425 
1.34538754675, 3.3689e-06, 9.86066e-06, -9.12075e-06, 1.18058e-05, 0.00334344, 0.00342207, 0.00332897, 0.00345504, 0.00165532, 0.00170412, 0.00164234, 0.00441903, 0.00459294, 0.00449357, 0.00339737, 0.00166596, 0.00451926, 0.00455153
1.34808186291, -1.99011e-06, 6.53026e-06, -1.18909e-05, 9.52337e-06, 0.00158065, 0.00166529, 0.0015657, 0.0017022, 0.000740644, 0.00078635, 0.000730052, 0.00219736, 0.00238191, 0.00212762, 0.00163783, 0.000750669, 0.00230171, 0.00217917

As you can see, the numbers are formatted differently and misaligned. Is there a way in vim to quickly align the columns properly, so that the result is this

1.33570301776,  3.61194e-06, 7.24503e-06, -9.91572e-06, 1.25098e-05, 0.0102828,  0.010352,   0.0102677,  0.0103789, 0.00161604, 0.00167978, 0.00159998, 0.00182596, 0.0019804,  0.0133687,  0.010329,   0.00163437, 0.00191202, 0.0134425 
1.34538754675,  3.3689e-06,  9.86066e-06, -9.12075e-06, 1.18058e-05, 0.00334344, 0.00342207, 0.00332897, 0.00345504,0.00165532, 0.00170412, 0.00164234, 0.00441903, 0.00459294, 0.00449357, 0.00339737, 0.00166596, 0.00451926, 0.00455153
1.34808186291, -1.99011e-06, 6.53026e-06, -1.18909e-05, 9.52337e-06, 0.00158065, 0.00166529, 0.0015657,  0.0017022, 0.000740644,0.00078635, 0.000730052,0.00219736, 0.00238191, 0.00212762, 0.00163783, 0.000750669,0.00230171, 0.00217917

That would be great to copy and paste sections with ctrl-v. Any hints?

Answer 1

If you're on some kind of UNIX (Linux, etc), you can cheat and filter it through the column(1) command.

:%!column -t

The above will parse on delimiters inside string literals which is wrong, so you will likely need pre-processing steps and specifying the delimiter for this file for example:

%!sed 's/","/&/' | column -t -s '&'
