Extract Data
Data extraction is the process of retrieving specific information from unstructured or semi-structured sources such as documents, web pages, or databases. AI agents excel at this task because they can parse complex formats, identify patterns, and output structured data without manual effort. Whether you need to pull key fields from PDFs, scrape tables from websites, or convert messy text into clean records, agents can handle it reliably and at scale.

Common questions
- How can I extract data from a PDF using an AI agent?
- Use a skill that reads PDF files and outputs structured fields like tables, key-value pairs, or text sections. The agent parses the document and returns the data in JSON or CSV format for easy integration.
- Can an AI agent extract data from multiple web pages automatically?
- Yes. Skills designed for web scraping can navigate pages, extract specified elements, and handle pagination. The agent outputs the collected data in a structured format, saving hours of manual copy-pasting.
- What types of data can be extracted with AI agents?
- Agents can extract text, numbers, dates, tables, lists, and even relationships between data points from sources like PDFs, HTML, emails, or databases. The output is typically structured as JSON or CSV.
