About HTML to JSON Converter

The HTML to JSON converter transforms an HTML document into a structured JSON representation of the DOM tree . This is ideal for web scraping pipelines, API backends, content migration, or any workflow where you want to analyze or store HTML as clean JSON data.

Key Features

• DOM Tree Representation: Converts HTML structure to nested JSON objects
• Attribute Extraction: Optionally include all HTML attributes
• Text Node Support: Extract text content from elements
• Pretty Printing: Format JSON with indentation for readability
• Complete Parsing: Handles all HTML elements and structures
• Nested Elements: Preserves parent-child relationships

How to Use

1. Input HTML: Paste your HTML code or upload an .html file
2. Configure Options: Choose formatting and content options
3. Review Output: The JSON output updates automatically
4. Copy or Download: Use the Copy or Download button to save your JSON

JSON Structure

Each HTML element is converted to a JSON object with the following properties:

• tag: The HTML tag name (lowercase)
• attributes: Object containing all HTML attributes (optional)
• children: Array of child elements and text nodes
• type: For text nodes, indicates "text" type
• content: For text nodes, contains the text content

Example Conversion

HTML Input:

<div class="container">
  <h1>Title</h1>
  <p>Text</p>
</div>

JSON Output:

{ 
  "tag": "div",
  "attributes": { "class": "container" },
  "children": [
    { 
      "tag": "h1",
      "children": [{ "type": "text", "content": "Title" }]
    },
    { 
      "tag": "p",
      "children": [{ "type": "text", "content": "Text" }]
    }
  ]
}

Common Use Cases

• Web Scraping: Extract structured data from HTML pages
• API Development: Convert HTML to JSON for API responses
• Data Analysis: Analyze HTML structure programmatically
• Content Migration: Transform HTML content to JSON databases
• Testing: Generate JSON fixtures from HTML templates
• Documentation: Create structured documentation from HTML

FAQ

• Does this preserve the visual layout of the page?
  No. The focus is on semantic structure and content. Layout and styling (CSS) are not represented in the JSON output.
• Can I use this JSON directly in my API?
  Yes. Many users wrap this DOM-style JSON inside their own API response structure, or post-process it to match their schema before serving it from an API.
• What about script and style tags?
  Those nodes are part of the DOM and can appear in the JSON tree, but typically you will filter them out in post-processing if not needed.
• Is this compatible with NoSQL databases?
  Yes. The nested object structure produced by this HTML to JSON converter works well with document stores like MongoDB, Firestore, CouchDB and others.

Privacy & Security

All HTML to JSON processing happens locally in your browser using the DOMParser API. Your HTML and resulting JSON never leave your device.
