Evidence · first-party tested/Best AI Tools for Extracting Structured Data from PDFs and Business Documents
The tool correctly extracts the bank statement currency as INR and includes citation metadata for that field.
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
Also checked on this input — same tool, 4 other criteria
Schema Adherence✓ WorkedReconstructs the bank statement into a nested JSON structure aligned to the requested schema, with document metadata, account, branch, statement period, transactions, summary, and rewards-style sections instead of flat OCR text.Semantic Field Enrichment✗ FailedLeaves derived transaction metadata incomplete, with transaction_type and transaction_id missing across transaction rows.Structural Clean Output◐ MixedExports JSON directly, but the bank workflow is not cleanly consumable end-to-end because the report says the result still needs reconciliation and correction before use.Table & Record Completeness✗ FailedDoes not preserve the repeating transaction table faithfully, returning 53 transaction records for a statement that contains 51 transactions.
