Description
JSON Lens is a fast, privacy-first JSON tool that runs entirely in your browser — your data never leaves your device. Paste or drag in any JSON and instantly: • Format, minify, or validate • View as an interactive tree, raw text, or an auto-flattened table • Locate errors down to the exact line & column • Handle large files without freezing (lazy rendering + smart row limiting) No sign-up, no install, no upload. It even works offline.
