Ruby - separating excel data contained in one column into individual columns [duplicate] - regex

Closed 8 months ago.
I'm trying to use Ruby to manipulate some excel data, but the .csv files I'm given have all of the data in one column.
The data has the headers and values separated by commas, but they are contained within the first column. Also, some of the values within the first column have text surrounded by quotes with commas inside the quotes.
Is there a way to separate the data within the first column into separate columns with Ruby?
I know you can do this in an excel, but I'd like to be able to do this in Ruby so I don't have to correct every .csv file manually.
I've included an example of the .csv file below.
The desired output would be:
{:header 1 => integer,
:header 2 => text,
:header 3 => "this text, has a comma within the quote"
:header 4 => integer}
I appreciate the help.

Here's one crude way to do it:
require 'csv'
result = []
csv = CSV.read('./file.csv')
headers = csv.shift
csv.each do |l|
hash = {}
hash[headers[0]] = l[0]
hash[headers[1]] = l[1]
hash[headers[2]] = l[2]
hash[headers[3]] = l[3]
result << hash
end
p result
[{"header 1"=>"integer",
"header 2"=>"text",
"header 3"=>"this text, has a comma within the quote",
"header 4"=>"integer"},
{"header 1"=>"integer",
"header 2"=>"text",
"header 3"=>"this text, has a comma within the quote",
"header 4"=>"integer"}]
This of course assumes that every row has 4 values.
Edit: Here is an example of actually writing the result to a file:
CSV.open('./output.csv', 'wb') do |csv|
result.each do |hash|
temp = []
hash.each do |key, value|
temp << "#{key} => #{value}"
end
csv << temp
end
end
