# Document processing

> Turn PDFs and scanned documents into typed rows for your production systems.

Operations teams use document processing agents to move information from invoices, contracts, forms, and scans into databases, ERPs, and review queues. Agno returns validated Pydantic objects from files and images. Workflows add approvals, batch execution, retries, and schedules.

Define a Pydantic schema and pass the document through `File`. The agent returns a validated instance of that schema.

```python theme={null}
from typing import List, Optional

from agno.agent import Agent
from agno.media import File
from agno.models.openai import OpenAIResponses
from pydantic import BaseModel, Field


class LineItem(BaseModel):
    description: str
    quantity: Optional[float] = None
    unit_price: Optional[float] = None
    amount: Optional[float] = None


class Invoice(BaseModel):
    invoice_number: Optional[str] = Field(None, description="As printed on the invoice")
    vendor: Optional[str] = None
    invoice_date: Optional[str] = None
    due_date: Optional[str] = None
    subtotal: Optional[float] = None
    tax: Optional[float] = None
    total: Optional[float] = None
    currency: Optional[str] = Field(None, description="ISO 4217, e.g. USD, EUR")
    lines: List[LineItem] = Field(default_factory=list)


agent = Agent(
    model=OpenAIResponses(id="gpt-5.5"),
    instructions=(
        "Extract invoice fields and line items from the attached PDF. "
        "Use exactly what the document shows. If a field is missing, "
        "leave it null. Do not guess."
    ),
    output_schema=Invoice,
)

result = agent.run(
    "Extract the invoice.",
    files=[File(url="https://example.com/invoice-1042.pdf")],
).content
# Invoice(invoice_number='1042', vendor='Acme Corp', invoice_date='2026-04-12',
#         due_date='2026-05-12', subtotal=1200.0, tax=96.0, total=1296.0,
#         currency='USD', lines=[LineItem(...), LineItem(...)])
```

`result` is a validated `Invoice` ready for an `INSERT`, an ERP call, or a queue message.
