How can I apply a function to all elements of a deep list?

Hello everyone,

Say I have a list of lists, whose depth is 5.

myLists = {{12.3, x, y, {w, z, "two"}},
  {67.4, {90.8, "this and that", {h, j, 56}}}}

You can see that some elements of the sublists are numbers, some are symbols, and some are strings. How can I convert all of the individual elements to strings by applying the ToString function?
