Lens · json
Walk a JSON file, not a wall of text.
A collapsible tree with types coloured, counts on folded nodes, a copyable path for every value, and a filter that keeps the ancestors of each match. Comments and trailing commas are tolerated; a broken file is reported by line rather than by character offset.

Files you open are remembered here, on this device, and are listed by every viewer. Nothing is sent anywhere — clearing them is permanent.
Tree or raw
Fold and unfold any branch, or switch to pretty-printed source with the same syntax colours.
Filter, not search
Typing keeps every matching row and the branches above it, so a match is never shown without its context.
Honest errors
A parse failure names the line and column and shows the offending text, instead of quoting a character offset.
