What it does
A tree instead of a wall of text
Fold a document down to the level you care about and read its shape at a glance.
Filter as you type
Match on keys or values and see only the rows that hit, with the path back to the root kept intact.
Built for files that hang the editor
Parsing and rendering happen off the UI thread, so a hundred-megabyte document scrolls the same as a small one.
Copy the JSONPath
Every row hands you the exact path to the value, ready to paste into a query or a test.
