Large JSON Viewer FAQ
How large a JSON file can it handle?
The viewer can handle JSON files up to several megabytes. Performance depends on your browser and device, but it's optimized for large payloads.
Can I search within the tree?
You can use the editor's built-in search (Ctrl/Cmd+F) to find specific keys or values, then switch to the tree viewer to explore the structure.
How does timestamp detection work?
Numeric values that look like Unix timestamps (seconds or milliseconds since epoch) and ISO 8601 date strings are automatically detected and shown with a human-readable date tooltip.
