About HTML to Ruby Converter

Convert HTML documents to Ruby code and data structures. Generate Ruby hashes, arrays, or Nokogiri builder code for HTML manipulation and web scraping in Ruby applications.

Key Features

  • Multiple Output Formats: Hash, Array, or Nokogiri builder code
  • Symbol Keys: Option to use Ruby symbols or strings for hash keys
  • Attribute Preservation: Includes HTML attributes in output
  • Nested Structure: Maintains HTML hierarchy in Ruby structures
  • Nokogiri Integration: Generates ready-to-use Nokogiri builder code
  • Text Content: Extracts and includes text content from elements

Output Formats

  • Ruby Hash: Nested hash structure with tag, attributes, text, and children
  • Ruby Array: Array-based representation [tag, attributes, text, children]
  • Nokogiri Builder: Executable Nokogiri::HTML::Builder code

How to Use

  1. Input HTML: Paste your HTML code or upload an .html file
  2. Select Format: Choose between Hash, Array, or Nokogiri output
  3. Configure Options: Enable symbols and attribute inclusion
  4. Review Output: The Ruby code updates automatically
  5. Copy or Download: Use the Copy or Download button to save your .rb file

Ruby Hash Format

Generates a nested hash structure:

{
  :tag => "div",
  :attributes => {
    :class => "container",
    :id => "main"
  },
  :text => "Content",
  :children => [...]
}

Ruby Array Format

Generates an array-based structure:

[
  "div",
  { :class => "container", :id => "main" },
  "Content",
  [...]
]

Nokogiri Builder Format

Generates executable Nokogiri builder code:

require 'nokogiri'

builder = Nokogiri::HTML::Builder.new do |doc|
  doc.div(:class => "container") do
    doc.h1("Title")
    doc.p("Content")
  end
end

html = builder.to_html

Common Use Cases

  • Web Scraping: Parse HTML for data extraction with Nokogiri
  • HTML Generation: Build HTML dynamically in Ruby applications
  • Template Conversion: Convert HTML templates to Ruby code
  • Data Structures: Represent HTML as Ruby data for processing
  • Testing: Create test fixtures from HTML samples
  • Rails Development: Generate view helpers and partials

Symbol vs String Keys

Symbols (recommended):

  • More idiomatic Ruby style
  • Better performance for hash lookups
  • Commonly used in Ruby frameworks like Rails

Strings:

  • Compatible with JSON serialization
  • Useful for dynamic key names
  • Better for external data interchange

Working with Nokogiri

To use the generated Nokogiri code:

  1. Install Nokogiri: gem install nokogiri
  2. Copy the generated Ruby code
  3. Run it in your Ruby application
  4. Modify the builder code as needed

Tips for Best Results

  • Clean HTML: Well-formed HTML produces cleaner Ruby code
  • Format Choice: Use Hash for data, Nokogiri for HTML generation
  • Symbols: Enable symbols for more idiomatic Ruby code
  • Attributes: Include attributes for complete HTML representation
  • Testing: Test generated code in your Ruby environment

Privacy & Security

All conversions happen locally in your browser. Your HTML is never uploaded to any server, ensuring complete privacy and security.
