Embedded YAML formatter (same-origin). Open standalone /yaml-formatter/ for a full-window bookmark.

Cross-tool handoff: ?in= carries base64url UTF-8 into this desk (query is stripped after load). Send from JWT Decoder (payload) or API Tester (response body, size-capped).

Sharing formatted JSON outside your browser tab? Strip common leak patterns first with Log redact (regex placeholders only — proofread yourself).
