vim , reformat text for programming

"The basic conversion is,

sed 's|^\([0-9]\)\(.*\)|{\1,""\2""}|g' file.txt > file2.txt

in vim,

:%s/\([0-9] \(.*\)/{\1,""\2""}/g

This will cover lines starting with the format,

N text on the line...

Where N is a single digit number.
Can be extended further for other forms."

"Does this vim command do what you want ?

%s/^\(.\)\ \(.*\)$/{\1,\ ""\2""},/g"
