Transform Document Images into Spreadsheets with LlamaParse

Problem

Converting document images such as receipts to structured spreadsheet data requires tedious typing and careful validation.

Solution

LlamaParse automates document data extraction by combining OCR parsing with schema validation, eliminating manual typing and human error.

Here is an example pipeline for extracting receipt data:

• Parse receipt images to markdown using LlamaParse OCR engine
• Define receipt structure with Pydantic models (company, date, items, totals)
• Extract structured data automatically with OpenAI integration
• Validate types and enforce business rules (positive prices, valid dates)
• Export to pandas DataFrames or spreadsheets for analysis
