GigaJSON: JSON viewer and formatter for large files

View large JSON responses with tree, table, search, JSONPath and jq. JSON content is processed locally in your browser.

Read JSON responses without fighting a wall of text. GigaJSON turns JSON pages into an interactive viewer with a searchable tree, sortable tables, graph exploration and powerful queries. Open an API response or JSON file in your browser and start exploring. BUILT FOR LARGE RESPONSES Parsing runs in a background worker, and the viewer renders the rows you need. Opening time and practical file limits depend on your device and the response size. EXPLORE YOUR DATA • Tree: expand and collapse objects, inspect values and copy paths. • Table: browse arrays of objects, sort columns and filter rows. • Graph: explore the structure of your document. • Text: read formatted JSON. • Query: use JSONPath, JMESPath or jq. • Find: search keys and values with Ctrl+F or Cmd+F. • Original: switch back to the original response. HANDLE REAL-WORLD FORMATS View JSON, NDJSON/JSON Lines, JSONP and responses with common anti-hijacking prefixes. Invalid JSON shows an error to help you identify the problem. Optional XML viewing supports feeds, sitemaps and XML responses. A FULL EDITOR IS INCLUDED Choose “Open in GigaJSON” to move a response into the bundled workspace. Edit data, apply transformations, compare documents, review history, generate TypeScript types or JSON Schema, and export in different formats. You can also right-click selected JSON or XML, or a link to a data file, and open it in GigaJSON. The bundled workspace works offline. LOCAL DATA PROCESSING Your JSON and XML content is processed on your computer and is not uploaded to GigaJSON or Google Analytics. Documents saved in the workspace remain in your browser’s local storage. No account is required. Usage statistics and error categories are enabled by default in Chrome. They are sent through GigaJSON’s analytics relay to Google Analytics, without document contents or the addresses of pages you view. You can disable this in the extension’s options by turning off “Share anonymous usage statistics.” CONTROL WHEN IT RUNS Turn automatic viewing on or off, exclude specific sites, and enable XML viewing in the extension’s options.
