Here is a very compact implementation:<\/p>\n

let to_str_list =\n  List.map (fun cs -> String.concat \"\" (List.map (String.make 1) cs))\n<\/code><\/pre>\n
It looks like this when your call it:<\/p>\n
# to_str_list [['h';'e';'l';'l';'o'];['w';'o';'r';'l';'d']];;\n- : string list = [\"hello\"; \"world\"]\n<\/code><\/pre>\n
Update<\/strong><\/p>\n
If you want to suppress empty strings at the outer level you can do something like this:<\/p>\n
let to_str_list css =\n  List.map (fun cs -> String.concat \"\" (List.map (String.make 1) cs)) css |>\n  List.filter ((<>) \"\")\n<\/code><\/pre>\n
It looks like this when you call it:<\/p>\n
# to_str_list [['h';'e';'l';'l';'o']; []; ['w';'o';'r';'l';'d']];;\n- : string list = [\"hello\"; \"world\"]\n<\/code><\/pre>\n<\/p><\/div>\n
