JSON
DataDefinition
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and machines to parse. It is the standard format for API responses and structured data exchange.
How It Relates to CrawlForge
JSON is the lingua franca of web data. API responses, configuration files, and structured data are almost universally encoded in JSON. When scraping, the goal is often to transform messy HTML into clean JSON that downstream systems can process.
CrawlForge tools return data in JSON format by default. Tools like scrape_structured and extract_structured let you define a JSON schema for the output, ensuring the extracted data matches your expected structure exactly.

Structured Output
Structured output refers to data returned in a predictable, machine-readable format like JSON, rather than free-form text. It enables reliable downstream processing by AI agents and data pipelines.
Structured Data
Structured data is information organized in a predefined format that makes it easy for machines to parse and understand. On the web, it typically refers to schema.org markup embedded in HTML pages.
