Search and replace in array of strings

Say I have an array (loaded from a .csv file) A = ["Aaaa", "BAaaa", "CAaaa"] and I want to make all the uppercase A's in to lowercase, i.e A = ["aaaa","Baaaa","Caaaa"].

My first guess was to use @enum in some way but apparently that only works on floats. I have tried to create a function which takes elements of A as arguments and then uses if/ifelse statements to check whether or not there is an uppercase A in there. But I can't figure out how to 'search and replace'.

Any advice is appreciated.

I guess you have an array of strings (your code was missing quotation marks), like this:

julia> A = ["Aaaa", "BAaaa", "CAaaa"]
3-element Array{String,1}:
 "Aaaa"
 "BAaaa"
 "CAaaa"

If this is the case this is the way to replace "A" with "a" in an array of strings:

julia> replace.(A, "A", "a")
3-element Array{String,1}:
 "aaaa"
 "Baaaa"
 "Caaaa"
