Extracts all 8 advertising line items as separate records, preserving the page-break continuation instead of merging or omitting rows.
What was measured
Table & Record Completeness
Are all tabular rows and line items extracted without merging, duplication, omission, or phantom records?
decisive for this rankingtransformation
Missing, duplicated, or merged rows and line items directly corrupt the structured dataset and break query results. (3 of 3 judges)
What was given, what came back
Test input: Invoice PDF · pdf · group: business-document-extraction
Input — what we sent
A two-page broadcast advertising invoice PDF with nested header metadata, billing and remit addresses, and eight line items spanning a page break. It was used to stress hierarchical line-item extraction, amount precision, time/day parsing, code extraction, and summary validation.
Why this input is hard
- · Nested line-item hierarchy extraction
- · Multi-page continuity across a page break
- · Precision on large dollar amounts and totals
- · Parsing complex time slots and day patterns
- · Extraction of Ad IDs and reconciliation codes
- · Mapping structured metadata sections correctly
- · Financial summary validation
- · Handling political advertising compliance text
Output — unretouched

Extraction Accuracy✗ FailedMisreads at least one alphanumeric identifier: line 1's source Ad-ID NRCCWI071005 is extracted as NRCCW1071005.Extraction Accuracy✓ WorkedExtracts invoice metadata and totals consistently, including invoice_number "4064621-1", invoice_date "10/28/12", aired_spots 8, gross_total 29750, and net_amount_due 25287.5.Extraction Accuracy✗ FailedLeaves several station-level fields null—address, city, state, postal_code, main_phone, and billing_phone—even though the station block is present in the schema and related info exists elsewhere in the invoice.Schema Adherence✓ WorkedReconstructs the invoice hierarchy into invoice_metadata, advertiser, station, billing_address, remit_address, flight_dates, line_items, and summary objects rather than returning flat OCR text.Semantic Field Enrichment✓ WorkedPopulates derived scheduling fields such as day_of_week "M" and days_pattern "MTWT" on invoice line items.Structural Clean Output✓ WorkedReturns directly consumable JSON for the invoice workflow, with the demo reaching extracted results and the report stating the JSON is immediately usable for integration.

Datalab✓ WorkedExtracts all eight invoice line items as separate records without merging, including rows that span the page break.Docsumo✓ WorkedThe line-item table keeps all 8 rows, including the row that spans the page break, without introducing a duplicate line item.Extend AI✓ WorkedIt extracts all 8 advertising line items as separate records, preserving item boundaries across the page break without merging adjacent rows.LlamaParse✗ FailedThe tool extracts invoice line items as structured rows, but it introduces an incorrect 8th line item with line_number 9, so the table record set is not fully faithful to the source invoice’s eight advertising records.Nanonets✓ WorkedKeeps all 8 advertising line items as separate records with no row merging or duplication.Reducto✓ WorkedExtracts all eight advertising line items as separate records and preserves the page-spanning table without merging adjacent rows.Retab✓ WorkedExtracts all 8 advertising line items as separate structured records without duplication or omission.Unstract✓ WorkedExtracts the line-item table without losing the row that crosses the page break; line 8 is returned in full with no duplication or data loss.
