Yes, it is easy to do something like this with an awk script...
Normally, a CSV file would have the same number of fields in every output line. There doesn't seem to be anything in your input file that indicates how many fields are present in the data. (We know that it is at least 101 fields, but we have no idea how many zero fields should appear at the ends each output line.) How is your script supposed to determine the number of fields to include in the output?
A CSV file also usually uses a comma as the field separator, but you seem to want a space character as the field separator. Is that correct?
Will there ever be anything other than :1 at the ends of the input fields (other than the 1st field)? For example, if a line had a lot of ones and a few zeros, could the input use fields ending with :0 instead of :1 to produce a shorter input line? Is all of the data you want to process in this same format? For example, the "diabetes" files on the site you referenced are in a completely different format.
Will each input line have the same number of fields as in your sample input? Or, can the number of ones in input and output lines vary?

h5fromh4
H5FROMH4(1) h5utils H5FROMH4(1)
NAME
h5fromh4 - convert HDF4 scientific datasets to an HDF5 file
SYNOPSIS
h5fromh4 [OPTION]... [HDF4FILE]...
DESCRIPTION
h5fromh4 takes one or more files in HDF4 format and outputs files in HDF5 format containing the datasets from the HDF4 files. (Currently,
only a single dataset per HDF4 file is converted.)
HDF4 and HDF5 are free, portable binary formats and supporting libraries developed by the National Center for Supercomputing Applications
at the University of Illinois in Urbana-Champaign.
A single h5 file can contain multiple data sets; by default, h5fromh4 creates a dataset called "data", but this can be changed via the -d
option, or by using the syntax HDF5FILE:DATASET with the -o option. The -a option can be used to append new datasets to an existing HDF5
file. If the -o option is used and multiple HDF4 files are specified, all the HDF4 datasets are output into that HDF5 file with the input
filenames (minus the ".hdf" suffix) used as the dataset names.
The most basic usage is something like 'h5fromh4 foo.hdf', which will output a file foo.h5 containing the scientific dataset from foo.hdf.
OPTIONS
-h Display help on the command-line options and usage.
-V Print the version number and copyright info for h5fromh4.
-v Verbose output.
-a If the HDF5 output file already exists, append the data as a new dataset rather than overwriting the file (the default behavior).
An existing dataset of the same name within the file is overwritten, however.
-o file
Send HDF5 output to file rather than to the input filename with .hdf replaced with .h5 (the default). If multiple input files were
specified, this causes all input datasets to be stored in file (rather than in separate files), with the input filenames (minus the
.hdf suffix) as the dataset names.
-d name
Write to dataset name in the output; otherwise, the output dataset is called "data" by default. Alternatively, use the syntax
HDF5FILE:DATASET with the -o option.
