JSONView Formatter Tool

JSONView is a clean JSON formatter and explorer for developers. Paste any raw JSON into the editor and the app instantly validates it and renders an interactive colour-coded tree — keys in blue, strings in green, numbers in amber, booleans in purple. Tap any node to collapse or expand nested objects and arrays. Tap any value to copy it. Error messages are shown inline when the input is malformed. Everything runs entirely on-device with no network calls.
