Quick Access — Common Fields
All field definitions are embedded in this page. No external lookups.

What it does: Accepts ISO 20022 XML messages (pacs.008, pain.001, camt.053, and more), auto-detects the message type from the XML namespace, validates structure against embedded schema rules, and parses every field with human-readable business context.

Why it exists: The SWIFT CBPR+ migration completed November 2025, Fedwire migrated in 2025, and every major RTGS system is now live on ISO 20022. Every bank, fintech, and payments engineer working with these messages needs a fast way to validate and understand them.

Data privacy: All parsing and validation runs in your browser using the native DOMParser API. Nothing is sent to any server. All validation rules and field definitions are embedded directly in this page.
