📝 HTML to JSON Smart Parser

🚀 Convert any HTML into structured JSON in seconds. Paste a URL, raw HTML, or upload an HTML file. AI extracts the fields you specify. No coding, no regex, no CSS selectors.

🕒 Last updated: 2026-04-16 · 🤖 AI-powered extraction · 📋 Custom field mapping · 🔗 URL + raw HTML · 🚫 No coding required

The HTML to JSON Smart Parser converts any HTML page into clean, structured JSON using AI. Provide a URL, paste raw HTML, or upload an HTML file, then specify which fields to extract. The AI reads the page and returns structured data matching your schema. No need to write CSS selectors, XPath, or regex patterns.

Built for data analysts, product teams, and developers who need to extract structured data from HTML pages without building custom parsers.

🎯 Target Audience	💡 Primary Use Cases
Data analysts, product teams, developers, no-code teams, researchers, automation builders	One-off data extraction, prototype scrapers, unstructured-to-structured conversion, HTML data mining

📋 What the HTML to JSON Smart Parser does

Three input modes with AI extraction:

• 🔗 URL mode. Paste a webpage URL and the Actor fetches and parses it.
• 📝 Raw HTML mode. Paste HTML content directly.
• 📄 HTML file mode. Upload an HTML file URL.
• 🤖 AI field extraction. Specify the fields you want and the AI maps them from the HTML.
• 📋 Custom system prompt. Guide the AI with additional instructions.

Each result returns the extracted fields as a flat JSON object matching your requested schema.

💡 Why it matters: writing CSS selectors or XPath expressions for every new page is tedious and breaks when HTML structure changes. This Actor uses AI to understand the page and extract the data you need, adapting to any HTML structure automatically.

⚙️ Input

Input	Type	Default	Behavior
url	string	""	Webpage URL to fetch and parse.
htmlContent	string	""	Raw HTML content to parse.
htmlFileUrl	string	""	URL to an HTML file to download and parse.
openAIApiKey	string	""	Your OpenAI API key for AI extraction.
model	string	"gpt-4o-mini"	AI model to use.
fieldsToExtract	string	""	Comma-separated field names to extract.
systemPrompt	string	""	Additional AI instructions.

Example: extract product data from a URL.

{
    "url": "https://www.example.com/product-page",
    "openAIApiKey": "sk-...",
    "fieldsToExtract": "title, price, description, rating, availability",
    "model": "gpt-4o-mini"
}

Example: parse raw HTML with custom prompt.

{
    "htmlContent": "<div class='listing'>...</div>",
    "openAIApiKey": "sk-...",
    "fieldsToExtract": "name, address, phone",
    "systemPrompt": "Extract contact information from business listings"
}

⚠️ Good to Know: you need your own OpenAI API key. The Actor sends the HTML to the specified model for extraction. Costs depend on your OpenAI usage and the HTML size.
