Document Parsing APIs
Document parsing goes past plain OCR to keep structure: tables, layout and named fields. LlamaParse converts PDFs, scans, Office files and spreadsheets to markdown or JSON for RAG, Unstructured also parses emails and can extract fields to a JSON schema, and Mindee targets invoices, receipts and IDs with ready-made field extraction.
