CSV到JSON Ruby脚本？

有人知道如何编写一个Ruby脚本，将csv文件转换成json文件吗

CSV将采用以下格式：

Canon,Digital IXUS 70,"Epic, Epic 100",3x,Yes (lockable),Yes (lockable),Yes
Canon, Digital IXUS 75,"Epic, Epic 100",3x,Yes (lockable),Yes (lockable),Yes
Canon,Digital IXUS 80,"Epic, Epic 100",3x,Yes (lockable),Yes (lockable),Yes

JSON需要产生以下结果：

{ "aaData": [
[ "Canon" , "Digital IXUS 70" , "3x" , "Yes (lockable)" , "Yes (lockable)" , "Yes"],
[ "Canon" , "Digital IXUS 75" , "3x" , "Yes (lockable)" , "Yes (lockable)" , "Yes"],
[ "Canon" , "Digital IXUS 80" , "3x" , "Yes (lockable)" , "Yes (lockable)" , "Yes"]
]}

这在ruby 1.9中很容易，其中数据是csv数据字符串

 require 'csv'
 require 'json'

 CSV.parse(data).to_json

从：

Year,Make,Model,Description,Price
1997,Ford,E350,"ac, abs, moon",3000.00
1999,Chevy,"Venture ""Extended Edition""","",4900.00
1999,Chevy,"Venture ""Extended Edition, Very Large""",,5000.00
1996,Jeep,Grand Cherokee,"MUST SELL!
air, moon roof, loaded",4799.00

到

这样做：

csv = CSV.new(body, :headers => true, :header_converters => :symbol, :converters => :all)
csv.to_a.map {|row| row.to_hash }
#=> [{:year=>1997, :make=>"Ford", :model=>"E350", :description=>"ac, abs, moon", :price=>3000.0}, {:year=>1999, :make=>"Chevy", :model=>"Venture \"Extended Edition\"", :description=>"", :price=>4900.0}, {:year=>1999, :make=>"Chevy", :model=>"Venture \"Extended Edition, Very Large\"", :description=>nil, :price=>5000.0}, {:year=>1996, :make=>"Jeep", :model=>"Grand Cherokee", :description=>"MUST SELL!\nair, moon roof, loaded", :price=>4799.0}]

信用证：

以Josh的例子为基础，您现在可以进一步使用：

现在，您可以调用

以立即使用它，或者将其写入格式良好的文件：

File.open('your/file.json', 'w') do |file|
  file.puts JSON.pretty_generate(transformed_data)
end

如果您在Rails项目中

CSV.parse(csv_string, {headers: true})
csv.map(&:to_h).to_json

我的解决方案就是这样结束的，与Mariu的非常相似

require 'csv'
require 'json'

csv_table = CSV.parse(File.read('data.csv'), headers: true)
json_string = csv_table.map(&:to_h).to_json

File.open('data.json','w') do |f|
  f.puts(json_string)
end

感谢1.8不起作用，我无法升级-1.87的正确语法是什么？安装gem'fastercsv'并将CSV更改为fastercsv
data=File.open（'/path/to/File.CSV'）。读取
分配数据
提取的数据=CSV.table（'your/File.CSV'，header\u converters:nil）
如果要将头保留为原始字符串，在普通Ruby中，
Ruby-e“需要'csv'；需要'json'”-e将csv.parse（File.open（ARGV[0]），{headers:true}.map（&:to_h）.to_json“example.csv
CSV.parse(csv_string, {headers: true})
csv.map(&:to_h).to_json

require 'csv'
require 'json'

csv_table = CSV.parse(File.read('data.csv'), headers: true)
json_string = csv_table.map(&:to_h).to_json

File.open('data.json','w') do |f|
  f.puts(json_string)
end
