Changing field separator/delimiter in exported CSV using Ruby CSV

Question

Is it possible to change the default field separator from comma to to some other character, e.g '|' for exporting?

Answer 1

Here's an example using a tab instead.

To a file:

CSV.open("myfile.csv", "w", {:col_sep => "\t"}) do |csv|   csv << ["row", "of", "CSV", "data"]   csv << ["another", "row"]   # ... end 

To a string:

csv_string = CSV.generate(:col_sep => "\t") do |csv|   csv << ["row", "of", "CSV", "data"]   csv << ["another", "row"]   # ... end 

Here's the current documentation on CSV: http://ruby-doc.org/stdlib/libdoc/csv/rdoc/index.html

Answer 2

The previous CSV library was replaced with FasterCSV in Ruby 1.9.

require "csv"  output = CSV.read("test.csv").map do |row|   row.to_csv(:col_sep => "|") end puts output
