Is it possible to convert a string of ASCII characters from a list of strings:

`[['You '], ['have '], ['made '], ['my '], ['day.']]`

I understand that the conversion is done using `ord(i)` as explained [here](https://stackoverflow.com/questions/227459/how-to-get-the-ascii-value-of-a-character). I just can't seem to figure out how to retain the list of list structure after the conversion that reads something like this:

`[[ 1, 2, 3 ], [ 1, 2, 3, 4 ], etc. ]`

Thank you!
