Does not derive transaction_type on the bank statement at all; the report states that transaction_type is null for every extracted transaction.
What was measured
Semantic Field Enrichment
Are derived fields such as transaction_type, transaction_id, cheque_number, day patterns, and ad codes correctly classified or extracted beyond raw OCR?
decisive for this rankingtransformation
For this ranking, correctly identifying derived business fields is part of producing usable structured data, not just a nice extra. (3 of 3 judges)

Bank Statement PDF
A four-page bank statement PDF with dense transaction tables, balance-forward bridges, account metadata, rewards data, and disclaimer text. It was used to stress schema-driven extraction, multi-page continuity, row completeness, and financial numerical accuracy.
Why this input is hard
- · Table extraction across 50+ transaction rows
- · Multi-page continuity with balance-forward bridges
- · Parsing structured account metadata alongside unstructured transaction descriptions
- · Numerical accuracy for deposits, withdrawals, running balances, and summaries
- · Extraction of nested rewards and disclaimer sections
Also checked on this input — same tool, 4 other criteria
Extraction Accuracy✓ WorkedCorrectly extracts high-level statement values, including account number 42710540422 and total deposits 70986.83, rather than corrupting the header fields.Schema Adherence✓ WorkedPreserves the supplied bank-statement hierarchy in structured JSON, with nested statement.metadata, account_holder, account, balances, transactions, summary, rewards, and disclaimers objects instead of flattening the document into OCR text.Table & Record Completeness✗ FailedLeaves the statement summary incomplete: total_transactions is null, and the report says the run extracted 47 transactions when the source contained 51.Table & Record Completeness✗ FailedFails to keep dense transaction rows fully distinct: the report says transaction descriptions were merged, dates were missing on 15+ transactions, and adjacent rows collapse into a single record on the highlighted statement crops.

Datalab◐ MixedClassifies bank-statement transaction_type inconsistently on merged rows: the 28 Jun record is labeled Deposit even though the visible row shows only a 399 withdrawal amount, and another merged row is labeled Deposit/Withdrawal.Extend AI✓ WorkedThe tool infers transaction direction from free text, classifying an ATM entry as `Withdrawal` and populating `withdrawal_amount: 1000`.Landing AI✓ WorkedClassifies extracted bank rows with semantic transaction_type labels such as Withdrawal and Deposit, showing derived type tagging beyond raw transaction text.LlamaParse✗ FailedThe tool does not reliably enrich bank transactions with derived identifiers or types: transaction_id and transaction_type are left empty across extracted records even when the descriptions contain transaction clues.Reducto✗ FailedDoes not consistently enrich transaction rows with schema-level fields such as transaction_type and transaction_id; the visible extracted rows remain partially populated and omit those fields.Retab✓ WorkedDerives transaction_type and transaction_id from the transaction narration, labeling the sample record as UPI with transaction_id 917615251879 instead of leaving only raw description text.Unstract✓ WorkedCorrectly enriches bank rows with transaction_type classification, with the report stating Withdrawal/Deposit was assigned correctly on all 51 transaction rows.
