Reconstructs 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.
What was measured
Schema Adherence
Does the output follow the supplied JSON schema hierarchy exactly, with correct nesting, field names, and data types?
decisive for this rankingtransformation
If the tool does not follow the supplied JSON schema exactly, the extracted data cannot be reliably used for structured querying or downstream automation. (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.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.Table & Record Completeness✓ WorkedExtracts all 8 advertising line items as separate records, preserving the page-break continuation instead of merging or omitting rows.

Datalab✓ WorkedThe invoice workflow can emit nested schema-shaped JSON with separate invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary objects rather than flat OCR text.Extend AI✓ WorkedThe tool reconstructs the invoice hierarchy into nested JSON with invoice_metadata, advertiser, station, summary, and line_items objects rather than returning raw OCR.LlamaParse✓ WorkedThe invoice output follows the supplied hierarchy closely, returning nested invoice_metadata, advertiser, station, line_items, and summary objects instead of a flat text dump.Nanonets✓ WorkedPreserves the requested invoice hierarchy, populating invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary as separate JSON objects rather than flattening the page.Reducto✓ WorkedReconstructs the requested nested invoice JSON rather than flattening the document, populating invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary sections.Retab✓ WorkedReconstructs the invoice schema into nested invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary sections rather than returning a flat document dump.Unstract✓ WorkedPopulates the invoice extraction into the requested hierarchy, separating invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary fields.
