Frequently Asked Questions

Is the JSON Viewer free to use?
Yes, the JSON Viewer is completely free with no limitations. View and explore JSON data of any size without registration or usage restrictions.
Is my JSON data secure when using this viewer?
Yes, all JSON viewing and parsing happens locally in your browser. Your data never leaves your device, making it safe to view sensitive configuration files, API responses, or any confidential JSON data.
What features does the JSON Viewer offer?
The JSON Viewer provides an interactive tree view of your JSON data with collapsible nodes, syntax highlighting, and the ability to expand or collapse nested objects and arrays. You can easily navigate complex JSON structures and copy specific values.
Can I search within my JSON data?
Yes, the viewer includes search functionality to find specific keys or values within your JSON. This is especially useful for large JSON files where manually scanning through data would be time-consuming.
What is the maximum JSON size I can view?
There is no artificial limit on JSON size. The viewer can handle large JSON files limited only by your browser's memory. For optimal performance with very large files, the tool uses efficient rendering techniques to keep the interface responsive.
