I made some blocks to convert strings and numbers to bytes and back

you can just drag the blocks screenshot into Snap! to get them
drag this into snap!

( le (4) byte uint @list to number ::list) //convert numbers from little endian(least significant digit first) whole numbers
( le (4) byte uint from (22) ::list)//convert numbers to little endian(least significant digit first) whole numbers
(utf-8 @list to string ::operators) //converts utf-8 to a string
(string [] to utf-8 ::operators) //converts a string to utf-8

cool!

added a base64 encode and decode block
