CSV::Row#to_h

row.to_h → hash

# File tmp/rubies/ruby-3.3.0/lib/csv/row.rb, line 653
def to_h
  hash = {}
  each do |key, _value|
    hash[key] = self[key] unless hash.key?(key)
  end
  hash
end

Returns the new Hash formed by adding each header-value pair in self as a key-value pair in the Hash.

Example

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.to_h # => {"Name"=>"foo", "Value"=>"0"}

Header order is preserved, but repeated headers are ignored:

Example

source = "Name,Name,Name\nFoo,Bar,Baz\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.to_h # => {"Name"=>"Foo"}
