🧩 HTML to JSON Smart Parser

🚀 Convert HTML into structured JSON in seconds. Bring your own OpenAI API key. URL fetch, paste HTML, or upload files. No bespoke parsers.

🕒 Last updated: 2026-05-09 · 🧠 BYO OpenAI key · 📥 URL / paste / file upload · 🔑 BYO model selection

Convert HTML into clean structured JSON without writing a parser per page. Provide one or more URLs, paste HTML directly, or upload HTML files, then specify (or auto-detect) which fields to extract. The actor sends the HTML to your OpenAI account using your API key, parses the response, and returns one structured record per input. Built for developers who want layout-agnostic HTML extraction without bespoke selector code.

You bring your own OpenAI API key, so all model usage is billed directly to your OpenAI account. Choose the model (gpt-4o, gpt-4o-mini, gpt-3.5-turbo, etc.) based on your accuracy and cost trade-offs.

👥 Built for	🎯 Primary use cases
Developers	Skip writing CSS selectors and XPath queries
Data engineers	Build layout-agnostic data pipelines
AI ops	Convert HTML into structured prompts for LLM workflows
Researchers	Index HTML archives without bespoke parsers
Content ops	Migrate HTML content into structured DBs
Indie devs	Add HTML parsing to side projects without a parser

📋 What the HTML to JSON Smart Parser does

🌐 Three input modes. URL fetch, paste raw HTML, or upload HTML file URLs.
🧠 AI-driven extraction. Sends HTML to OpenAI with your key for layout-agnostic parsing.
🎯 Field selection. Specify which fields to extract or let the AI auto-detect.
🤖 Model choice. gpt-4o, gpt-4o-mini, gpt-4-turbo, gpt-3.5-turbo, or gpt-5 when available.
✏️ Custom prompts. Optional system prompt to bias the extraction.
🆔 Per-input metadata. Each record carries the source URL, prompt, and timestamp.

The actor processes inputs in the order you provide them. Records stream into the dataset as parsing completes.

💡 Why it matters: writing a parser per page type costs hours and breaks with every layout change. AI-driven extraction adapts to layout variation without code changes, so dev teams can ship structured-data features faster.

🎬 Full Demo

🚧 Coming soon: a 3-minute walkthrough showing URL input, custom field extraction, and how to feed the output into a downstream pipeline.

⚙️ Input

Field	Type	Name	Description
url	array	URL (Fetch HTML)	URLs to fetch HTML from. The actor does a plain HTTP GET.
htmlContent	string	HTML Content (Paste)	Optional. Paste raw HTML directly.
htmlFileUrl	array	HTML File URL (Upload)	Optional. URLs to uploaded HTML files.
openAIApiKey	string	OpenAI API Key	Required. Your OpenAI API key. The actor uses this for the model call.
model	enum	OpenAI Model	gpt-4o-mini (default), gpt-4o, gpt-4-turbo, `gpt-3.5-turbo`, gpt-5.

Example 1. URL extraction with default model.

{
"url":[{"url":"https://books.toscrape.com/catalogue/a-light-in-the-attic_1000/index.html"}],
"openAIApiKey":"sk-...",
"model":"gpt-4o-mini"
}

Example 2. Paste HTML directly.

{
"htmlContent":"<html><body><h1>Title</h1><p>Body</p></body></html>",
"openAIApiKey":"sk-...",
"model":"gpt-4o"
}

⚠️ Good to Know: you must supply your own OpenAI API key. All model usage is billed to your OpenAI account.

📊 Output

The dataset returns one structured record per input. Each record carries the source identifier, extracted JSON, the model used, and a timestamp. Consume the dataset as JSON, CSV, Excel, XML, or RSS via the Apify console or API.

🧾 Schema

Field	Type	Example
🌐 sourceUrl	string (url) or null	`https://books.toscrape.com/.../1000/index.html`
📦 parsedData	object	`{"title":"A Light in the Attic","price":51.77,"availability":"In stock"}`
🤖 model	string	gpt-4o-mini
🎯 prompt	string	`Extract title, price, and availability`
📅 timestamp	ISO datetime	`2026-05-09T12:00:00.000Z`
❗ error	string or null	null

📦 Sample records

1. URL extraction (book product page)

{
"sourceUrl":"https://books.toscrape.com/catalogue/a-light-in-the-attic_1000/index.html",
"parsedData":{
"title":"A Light in the Attic",
"price":51.77,
"availability":"In stock",
"rating":"Three",
"description":"It's hard to imagine a world without A Light in the Attic..."

"sourceUrl":null,
"parsedData":{
"title":"Welcome",
"body":"Today we launched our new product..."
},
"model":"gpt-4o",
"timestamp":"2026-05-09T12:00:00.000Z",
"error":null
}

3. Failed parse (missing API key)

{
"sourceUrl":"https://example.com/page.html",
"parsedData":null,
"model":"gpt-4o-mini",
"timestamp":"2026-05-09T12:00:00.000Z",
