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.
