Is there any way to convert a comma separated string into an array in Ruby? For instance, if I had a string like this:
"one,two,three,four" How would I convert it into an array like this?
["one", "two", "three", "four"]

To convert a comma separated string to a numeric array:Call the split() method on the string to get an array containing the substrings. Use the map() method to iterate over the array and convert each string to a number. The map method will return a new array containing only numbers.
Use the split method to do it:
"one,two,three,four".split(',') # ["one","two","three","four"] If you want to ignore leading / trailing whitespace use:
"one , two , three , four".split(/\s*,\s*/) # ["one", "two", "three", "four"] If you want to parse multiple lines (i.e. a CSV file) into separate arrays:
require "csv" CSV.parse("one,two\nthree,four") # [["one","two"],["three","four"]] 
require 'csv' CSV.parse_line('one,two,three,four') #=> ["one", "two", "three", "four"] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
