I kept hitting JSON buried inside log lines and API payloads — strings of escaped JSON inside JSON — and most formatters stop at the first level. NextJSON decodes every level into a collapsible tree, all client-side with no sign-up. Try pasting a messy escaped payload first, then the diff and JSON Schema tools.
