Evidence · first-party tested/Best AI Tools for Extracting Structured Data from PDFs and Business Documents
Leaves some transaction value_date fields blank even where the statement shows dates in that column, so transaction metadata is incomplete.
What was measured
Extraction Accuracy
Are field values correct, complete, and free of OCR or parsing errors? Includes numerical precision on financial fields.
decisive for this rankingtransformation
The whole point is to pull the right values from documents; wrong or incomplete field values mean the tool failed at the job. (3 of 3 judges)
What was given, what came back
Test input: Bank Statement PDF · pdf · group: financial-document-extraction
Input — what we sent
A 4-page bank statement PDF with 51 transactions, balances, rewards, and disclaimer text, used to test schema-driven extraction of dense financial tables and multi-page continuity.
Why this input is hard
- · Table extraction across 50+ transaction rows
- · Multi-page continuity with BALANCE FORWARD bridges
- · Structured metadata vs. free-text transaction descriptions
- · Numerical accuracy for balances, deposits, withdrawals, and summaries
- · Nested schema population for account, branch, balances, rewards, and disclaimers
Output — unretouched
No output artifact
The verdict rests on the tester's written observation alone — no file was captured for this cell.
Also checked on this input — same tool, 4 other criteria
Schema Adherence✓ WorkedKeeps a nested statement schema intact, emitting separate metadata, account_holder, account, branch, statement_period, balances, transactions, summary, rewards, and disclaimers objects instead of flattening the document.Semantic Field Enrichment✗ FailedFails to derive transaction-level fields, leaving transaction_id and transaction_type empty even for descriptions that encode ATM, UPI, and CRADJ cues.Table & Record Completeness✓ WorkedExtracts the bank statement's rewards section as structured repeated records, including accountNumber, titleDate, scheme, openingBalance, pointsAccrued, pointsRedeemed, adjustments, and closingBalance.Table & Record Completeness✗ FailedOver-segments the bank-statement transaction table, outputting 54 transaction rows for a statement the report says contains 51 transactions and leaving the summary at 44 total_transactions, so row counts are not self-consistent.
