FAQ
- Does this guarantee the bank will accept my file?
- No. Banks run additional compliance checks. This tool helps you catch structural issues before submission.
- Can I lint other ISO 20022 messages?
- Yes—pain.002 and camt messages often share namespaces. Extend the validator with custom schemas as needed.
- Where do you store my file?
- Nowhere. Validation happens locally in the browser and nothing is uploaded to a server.
