Exclude headers when importing Google Spreadsheet content with Roo - ruby-on-rails

Question

I created a rake task to import users from a Google Sheet. Therefore I am using the gem 'Roo'. Everything works so far but I can't seem to get it working without importing the first row (headers).
This is my code:
require 'roo'
namespace :import do
desc "Import users from Google Sheet"
task users: :environment do
#counter = 0
url = 'https://docs.google.com/spreadsheets/d/{mycode}/export?format=xlsx'
xlsx = Roo::Spreadsheet.open(url, extension: :xlsx, headers: true)
xlsx.each do |row|
n = User.where(name:row[0]).first
user = User.find_or_create_by(id: n)
user.update(
name:row[0],
country_id:row[6]
)
user.save!
puts user.name
#counter += 1
end
puts "Imported #{#counter} lines."
end
end

Answer 1

Your code says headers: true when you are opening the sheet. Have you tried turning it to false? Or are you saying it does not work when it's set to false?
Also, you are using .each rather differently than the example in the documentation. The doc shows a hash with keys derived from the headers. You are using [n] array notation. Does that work?
EDIT:
Try using .each in a way that's more similar to what the documentation says:
xlsx.each(name: 'Name', country_id: 'Country ID') do |row|
n = User.where(name: row[:name]).first
...
end
The strings 'Name' and 'Country ID' are just examples; they should be the text of whatever column headers have the name and country_id information.

There is a way to skip the headers, it is using the method: each_row_streaming(offset: 1).
It will return an array with rows skipping the header, so you have to get the value using .value method. In documentation specify it for Excelx::Cell objects, but it works for Roo::Spreadsheet objects too.
The documentation example:
xlsx.each_row_streaming(offset: 1) do |row| # Will exclude first (inevitably header) row
puts row.inspect # Array of Excelx::Cell objects
end
