ISO 20022 100 — Free Sample (10 records)

This is a free 10-record sample of the full 100-record commercial dataset. Every record in this sample is a real, valid bfsi record — real records, just the data. you'd build by hand.

What's in this sample

• 10 records in records.jsonl (NDJSON, one record per line)
• Schema-validated: every record parses against the real industry-standard schema before publishing
• Ready to use: import directly into any bfsi pipeline — no transformation step needed
• Format: standard JSON Lines (.jsonl), bfsi-native structure

Why these records hold up

Most synthetic datasets are "good enough" — they look like the right shape, but fail against real-world parsers. Cottonwood Development's datasets are generated and validated against the actual schema:

• Healthcare records validate as valid FHIR R4 Patient resources
• Banking messages parse against the ISO 20022 pacs.008.001.10 XSD
• CRM records maintain referential integrity (customer → orders → line items)
• Invoice records have internally-consistent totals (subtotal + tax = total)

Every record passes schema validation before publishing. If it doesn't parse against the real spec, it doesn't ship.
