Smart Field Detection - Automatically identifies and extracts important fields from product pages, articles, profiles, etc.
Custom Field Selection - Specify exactly which fields you want extracted, or let AI choose what's important
Clean JSON Output - Well-structured, ready-to-use JSON data
Support for Any HTML - Works with product pages, articles, listings, profiles, and any HTML content
Fast and Accurate - AI-powered extraction that understands context and meaning

Business Value: Save hours of manual HTML parsing and data extraction. Automatically extract meaningful information from HTML documents, web pages, or HTML snippets into structured JSON format instantly, enabling easy data analysis, integration, and processing.

How to use the HTML to JSON Scraper - Full Demo

Watch this 3-minute demo to see how easy it is to get started!

Input

To start converting HTML to JSON, simply fill in the input form. You can convert HTML content by providing:

url (Fetch HTML) - Enter a URL to fetch HTML content directly from a website. This makes a simple HTTP GET request to fetch the HTML. Important: This is a simple HTTP request with no JavaScript execution or Cloudflare/bypass protection. If the page has protection (e.g., Cloudflare, bot detection, CAPTCHA), it will not retrieve any data. Leave empty if pasting HTML or uploading a file.
htmlContent (Paste) - Paste your HTML content directly into the text area. This can be any HTML content, from simple snippets to complete web pages. Leave empty if using URL or uploading a file.
htmlFileUrl (Upload) - Upload an HTML file using the file upload button. The file will be automatically processed. Leave empty if using URL or pasting HTML content.
openAIApiKey - (Required) Your OpenAI API key. You can get one from OpenAI Platform.
model - Select the OpenAI model to use for extraction. Options include gpt-5, gpt-4o, gpt-4o-mini, gpt-4-turbo, and gpt-3.5-turbo. Defaults to gpt-4o-mini for cost-effective extraction.
fieldsToExtract - (Optional) Specify which fields you want extracted (e.g., "title, price, description, images, specifications"). If not provided, the AI will automatically extract all important fields it identifies. Separate multiple fields with commas.
systemPrompt - (Optional) Custom system prompt to guide the AI extraction. If not provided, a smart default prompt will be used that extracts meaningful information from the HTML.
maxItems - (Optional) Maximum number of items to process. Leave empty for unlimited (paid users only). Free users must specify this parameter and are limited to 100 items.

Here's what the filled-out input schema looks like:

Input Configuration

And here it is written in JSON:

{
    "url": [""],
    "htmlContent": ["<html><body><h1>Sample Title</h1><p>Sample content</p></body></html>"],
    "htmlFileUrl": [""],
    "openAIApiKey": "",
    "model": "gpt-4o-mini",
    "fieldsToExtract": ["title", "price", "description", "images"],
    "systemPrompt": "",
    "maxItems": 10
}

Output

After the Actor finishes its run, you'll get a dataset with the output. The length of the dataset depends on the HTML content you provided. You can download those results as an Excel, HTML, XML, JSON, and CSV document.

Here's an example of converted JSON data you'll get if you provide HTML content:

Output Example

{
    "title": "Sample Title",
    "content": "Sample content",
    "description": "This is a sample description extracted from the HTML",
    "price": "$99.99"
}

Frequently Asked Questions

Q: How does it work? A: HTML to JSON Scraper is easy to use and requires no technical knowledge. Simply paste your HTML content or upload an HTML file, provide your OpenAI API key, and optionally specify which fields to extract. The AI will intelligently extract meaningful information from your HTML and convert it to structured JSON.

Q: What's the difference between this and a regular HTML parser? A: This tool doesn't just convert HTML tags to JSON structure. Instead, it uses AI to understand the content and extract meaningful information. For example, on a product page, it will extract the actual product title, price, description, and specifications - not just convert the HTML divs and spans to JSON.

Q: Can I specify which fields to extract? A: Yes! You can specify which fields you want extracted (e.g., "title, price, description, images"). If you don't specify fields, the AI will automatically extract all important fields it identifies from the HTML.

Q: How accurate is the conversion? A: The AI-powered conversion uses advanced machine learning to understand HTML structure and extract data accurately. The conversion quality depends on the HTML structure and complexity.

Q: Can I use my own OpenAI API key? A: Yes, you need to provide your own OpenAI API key. You can get one from OpenAI Platform.

Q: What HTML formats are supported? A: The scraper supports any HTML content format, from simple snippets to complete web pages. The AI will intelligently extract and structure the data.

Q: Can I customize the conversion? A: Yes, you can provide a custom system prompt to guide the AI conversion process and specify what data to extract.

Q: Can I fetch HTML from any URL? A: The URL option makes a simple HTTP GET request with no JavaScript execution or protection bypass. If a website has protection (e.g., Cloudflare, bot detection, CAPTCHA), the request will not retrieve any data. For protected pages, you should download the HTML manually and use the htmlContent or htmlFileUrl option instead.

Q: What if I need help? A: Our support team is here to help you get the most out of this tool. Contact us through the Apify platform for assistance.

Q: Is my data secure? A: Your HTML content and API key are processed securely. The data is only used for the conversion process and is not stored or shared.
