将带有标题的CSV转换为哈希数组

Posted 2021-02-23

To be improved to work with fasterCSV

require 'csv'
 
csv_data = CSV.read 'data.csv'
headers = csv_data.shift.map {|i| i.to_s }
string_data = csv_data.map {|row| row.map {|cell| cell.to_s } }
array_of_hashes = string_data.map {|row| Hash[*headers.zip(row).flatten] }
