file_stat

$ cat A9E27.txt
person,42%
person,60%
$ cat ffn2eG6.txt
train,85%
etc etc
how can I create a file that is like this
1, A9E27.txt, person,42%, person,60%
2, ffn2eG6.txt, train,85%
3, ...

where 1 shows the file number when I sort my file names alphabetically something like ls -1 | sort
and A9E27.txt is the file name, and each line of file contents comes in front of it separated by comma
