SWIFT MT & ISO 20022 viewer
Read MT messages block by block, or ISO 20022 payment XML — recomputing the total against the declared control sum.
Handles SWIFT MT block structure and ISO 20022 payment XML, detected automatically. For ISO 20022 it recomputes the total and checks it against the declared CtrlSum and NbOfTxs — a mismatch there is one of the most common reasons a bank rejects a payment file outright. Payment instructions are among the most sensitive files an integration layer carries: everything here is parsed in your browser and nothing is transmitted, but use a de-identified message where you can.

These exist because the underlying problem is real. If the numbers you just put in look uncomfortable, that is usually worth a conversation.
