What was measured

Extraction Accuracy

Are field values correct, complete, and free of OCR or parsing errors? Includes numerical precision on financial fields.

Input — what we sent

Input not captured

This run recorded no prompt or input file for the test, so we cannot show you what produced the result below. Capture gaps are tracked, not hidden.

A 2-page broadcast advertising invoice PDF with 8 line items, complex time/day fields, large dollar amounts, and compliance text, used to test hierarchical line-item extraction and financial validation.

Why this input is hard

· Nested line-item hierarchy extraction
· Multi-page line-item continuity across a page break
· Large dollar amount precision and total validation
· Parsing time slots, day patterns, and air dates
· Extraction of alphanumeric ad IDs and reference codes
· Structured metadata mapping for advertiser, station, billing, and remit sections
· Political advertising and FCC compliance text recognition

Schema Adherence✓ WorkedReconstructs the invoice into the requested nested JSON hierarchy, populating invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary sections.Schema Adherence◐ MixedLeaks schema-unrequested fields into the invoice export, including idb_number, so the output is not strictly constrained to the provided schema.Semantic Field Enrichment✓ WorkedSurfaces derived line-item metadata as structured fields, including frequency = 1x with citation support.Table & Record Completeness✓ WorkedKeeps all 8 invoice line items as separate structured rows without merging adjacent entries.
