An incredibly fast, local JSON data tool. Not only preview massive payloads instantly, but also convert them into an interactive, sortable data table with one click.
When dealing with massive JSON arrays from APIs or database exports, reading raw text is nearly impossible. Our completely local JSON viewer instantly parses your data into a highly interactive table, allowing you to sort, analyze, and convert JSON to CSV without ever uploading your sensitive data to a server.
Unlike traditional web tools that crash when you paste large JSON strings, our engine uses virtualized rendering. This means you can view hundreds of thousands of rows of JSON data in a perfectly formatted grid smoothly, natively in your browser.
