Extracts bank-statement account and balance fields into correctly typed values, including account holder 'MR SEENIVASAN', account number '42710540422', opening_balance 114453.65, and closing_balance 116149.46.
What was measured
Extraction Accuracy
Are field values correct, complete, and free of OCR or parsing errors, including numerical precision on financial fields?
decisive for this rankingtransformation
Correct field values are the core of the job; wrong or incomplete extraction means the tool failed to retrieve the structured data from the document. (3 of 3 judges)
What was given, what came back
Test input: Bank Statement PDF · pdf · group: business-document-extraction
Input — what we sent
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
Output — unretouched
Also checked on this input — same tool, 4 other criteria
Schema Adherence✓ WorkedReconstructs the supplied bank-statement schema into a nested JSON object with separate statement.metadata, account_holder, account, branch, balances, transactions, summary, rewards, and disclaimers sections instead of flattening the document into OCR text.Semantic Field Enrichment✓ 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.Structural Clean Output✓ WorkedProduces directly copyable JSON from the workflow, so the bank-statement extraction is immediately usable without a transformation layer after configuration.Table & Record Completeness◐ MixedOvercounts the bank-statement transaction table in the summary, reporting total_transactions 43 when the researcher says 40 should be counted after excluding balance-forward, tax, and charge entries.

Datalab⚠ StruggledMisplaces a bank-statement transaction across dates: a row that belongs to 18 Jun is attached to the 19 Jun record after merging, so date association is unreliable.Docsumo◐ MixedIn the rewards scheme table, zero-value cells render as blank rather than as 0, so the extractor preserves the row structure but loses explicit zero values.Extend AI✗ FailedThe summary aggregation is incorrect: `total_transactions` is 49 in the output, while the report says the expected count after exclusions is 40.Landing AI✓ WorkedPreserves statement metadata and balances with exact values, including bank_name "Standard Chartered", statement_date "16 Jul 2019", currency "INR", opening_balance 114453.65, and closing_balance 116149.46.LlamaParse⚠ StruggledThe tool leaves value_date blank on some bank transactions even though the source statement contains value dates, so transaction metadata is only partially accurate.Nanonets✓ WorkedCorrectly extracts high-level statement values, including account number 42710540422 and total deposits 70986.83, rather than corrupting the header fields.Reducto✓ WorkedCorrectly extracts the bank statement currency as INR and attaches high-confidence citation metadata, with extract confidence shown as 0.984.Unstract✗ FailedUnderstates the derived bank-summary count: summary.total_transactions is reported as 43 even though the PDF contains 51 transactions, a 16% undercount.
