Is there a sed command I can run that can convert the space/(s) after
the last digit of the
number ONLY to a single tab
Any sed examples would be greatly appreciated.
You asked a similar question in comp.lang.awk just before. Would you
explain why you want specifically a sed solution here? You can of
course do it entirely in shell as well.

while read -r num rest
do printf "%d\t%s\n" "$num" "$rest"
done < your_file

My output should look like this:
10<tab>Jane<space> A.<apace> Doe
15<tab>John<space>Q.<space>Public
Note that <space> is a literal space ' ' and <tab> is a literal tab.

After I posted in the awk room I realized that this is basically a
substitution and this would be better for sed, at least thats what I
thought. As for doing it in the shell I would prefer just to pass my
commands thru a pipe and deal with on file only to keep things simple
instead of using two file names

My command is basicially something liek this
cat file | sort | uniq -c > file1

(Useles use of cat! Instead write this as

sort file | uniq -c > file1

And adding your additional commands to the shell code that I posted above

sort file | uniq -c |
while read -r num rest
do printf "%d\t%s\n" "$num" "$rest"
done > file1


Doing it in the shell would require me to now read file1 and print to
file2 and remove file thats why I thought the pipe
would be better.

You have quite some misconceptions here.
