About JSON Editor - Viewer & Format

JSON Viewer & Editor is the most powerful JSON tool for mobile devices. It auto-detects JSON on your clipboard and lets you view it instantly with one tap. Explore complex JSON structures with an interactive, expandable tree view that color-codes strings, numbers, booleans, and null values. The formatted view shows pretty-printed JSON with line numbers and syntax highlighting. Need to edit? Switch to the built-in editor with smart keyboard shortcuts for brackets, quotes, colons, and common values. Validate your JSON in real-time and see error locations highlighted. Convert JSON to YAML, CSV, or key-value format with a single tap. JSONVEdit also includes file support (open .json files), search within JSON trees, expand/collapse all nodes, and JSON statistics (key count, depth, size). Auto-saved sessions mean you never lose your work.
