Schema for aligned documents

The tree for formatted JSON confirms pretty-print did not change data. Verify keys, field order, and types after indentation changes.

Navigate objects and arrays

Hierarchy matches the text view but navigates faster with collapse. Structural issues show as empty branches or nulls.

Handy when diffing two config versions without two walls of text.

Preview values and copy paths

Strings show a prefix; numbers and booleans show fully. Paths copy into scripts and tests.

Links formatter output to real fields in your codebase.

Collapse or expand branches

Collapse the root array and open only the failing element—less scrolling on mobile.

Works offline after the first load when you analyze logs in the field.
