Parse emails, PDFs, and documents into structured JSON with LLM-powered extraction
Describe the fields you need in natural language and Airparser extracts them into consistent JSON from PDFs, emails, images, and Office documents.
Forward messages and their attachments to a dedicated address, and Airparser turns each one, plus anything attached, into structured data automatically.
Clean, reshape, enrich, or filter extracted values with Python code, or let the AI code assistant generate it from a plain-language description.
Push parsed records to 7,000+ apps through Zapier, Make, and n8n, or connect directly with REST APIs, webhooks, Google Sheets, Airtable, and Excel.
