VB-PUO Validator: check a SIVI message in your browser
Free validation of SIVI VB-PUO messages against the official JSON schemas of Release 2026 (001.04) and Release 2027 (001.05), including code lists and the consistency checks from the manual. Your file never leaves your computer.
What is checked: JSON syntax, the JSON schema of the chosen message and release (mandatory fields, types, formats, lengths, decimals, unknown fields, entityType), the AFD code lists (AFDIDP, AFDRES, AFDCAE, AFDSWI, ISOVAL) and the consistency checks from the manual: cohort sum equals scheme total, exactly one of tradeAmount and tradeQuantity, switch pairs, positive amounts, startAge and endAge, reporting period, reserve fields, chunking, afdDefinitionVersion and IBAN/BIC format.
Need more than a validator?
The WTP Data Lab platform validates, visualises and exchanges SIVI messages for several funds and counterparties at once, with feedback handling, missing-message monitoring per month-end and tolerance monitoring, beside your core system and without touching it.
