How do I save my dictionary as a .csv (or excel) file?

This is easily done with the CSV package (If you don’t have it, run Pkg.add(“CSV”) in your REPL)

using CSV
test = Dict("a"=>1, "b"=>2, "c"=>3)
CSV.write("test.csv", test)

You can add a file-path like this: “/Users/your/custom/location/test.csv”
