It extracts all 8 advertising line items as separate records, preserving item boundaries across the page break without merging adjacent 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


Also checked on this input — same tool, 5 other criteria
Extraction Accuracy✗ FailedIt over-reads the payment-term field, outputting `Payment Terms 30 Days` instead of the requested `30 Days`.Schema Adherence✓ WorkedThe tool reconstructs the invoice hierarchy into nested JSON with invoice_metadata, advertiser, station, summary, and line_items objects rather than returning raw OCR.Semantic Field Enrichment✓ WorkedThe tool correctly derives higher-level line-item fields such as `day_of_week: Tu` and `days_pattern: -T----` alongside ad ID, reference number, and flight-period dates.Structural Clean Output✓ WorkedThe invoice output includes per-section OCR confidence metadata alongside the extracted fields while remaining machine-readable JSON that can be consumed without structural transformation.Structural Clean Output✗ FailedIt does not preserve the declared schema order, so the JSON is not directly consumable by order-sensitive pipelines without extra reshaping.

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.Landing AI✓ WorkedExtracts all 8 advertising line items as separate records, preserving the page-break continuation instead of merging or omitting 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.
