# Convert HTML table into Json

json = Jsoner.parse(html)

# output json => 
# 
#   [ {"First Name"=>"Jill", "Last Name"=>"Smith",   "Points"=>"50"},
#     {"First Name"=>"Eve",  "Last Name"=>"Jackson", "Points"=>"94"},
#     {"First Name"=>"John", "Last Name"=>"Doe",     "Points"=>"80"},
#     {"First Name"=>"Adam", "Last Name"=>"Johnson", "Points"=>"67"} ]

Or, Jsoner can parse HTML file including HTML table

require 'open-uri'
# you must have table.html file and assign file path correctly.

table = Jsoner.parse(open('table.html'))

# output json => 
# 
#   [ {"First Name"=>"Jill", "Last Name"=>"Smith",   "Points"=>"50"},
#     {"First Name"=>"Eve",  "Last Name"=>"Jackson", "Points"=>"94"},
#     {"First Name"=>"John", "Last Name"=>"Doe",     "Points"=>"80"},
#     {"First Name"=>"Adam", "Last Name"=>"Johnson", "Points"=>"67"} ]

Or you can open Link

require 'open-uri'

table = Jsoner.parse(open('http://www.w3school.com.cn/tiy/t.asp?f=html_table_header'))

# output json => 
#
# [{"姓名"=>"Bill Gates", "电话"=>"555 77 855"}]
