Structured Data vs PDF Extraction
Plain-language summary
Structured data gives software an explicit data model. PDF extraction tries to infer structure from visual layout.
Why extraction can fail
- Layouts vary across templates and vendors
- Labels and field positions can shift
- Parsing logic can break on minor document changes
Why structured data is more reliable
- Field meaning is declared, not guessed
- Validation can be run against known rules
- Downstream systems can process data consistently
Practical outcome
Keeping structured data with the report reduces brittle workflows and improves interoperability, data fidelity, and model readiness.
