Jayson is a JSON viewer and editor for iPhone and iPad. Browse JSON as a structure, edit values, and save your changes back to the file. Whether you're inspecting an API response, checking a config file, or making a quick fix on the go, Jayson turns raw JSON into something you can actually read and change. BROWSE AND EDIT - Open JSON files stored on your device or in iCloud Drive. - Toggle between a structured table view and syntax highlighted text. - Add new values and keys, and save your changes back to the file. - Parse text or the contents of a URL from your clipboard into JSON. - Highlight a key from a child of an array to get a quick overview of your data. TABS, SPLITS, AND WINDOWS - Switch between files, or different objects in a single file, using tabs. - Compare JSON in a single file or across files using multiple splits. - Open multiple windows on the iPad. WORKS WITH SHORTCUTS Jayson integrates with Shortcuts, which comes in handy for debugging API calls, previewing JSON files, and building workflows around JSON. - Pass a response from Get Contents of URL to Jayson to see how it is structured. - Open JSON as a document you keep working on, or as a temporary preview. - Format JSON and hand the result to the next action, using spaces or tabs.
