Jayson vs JSON Scope

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. FREE, WITH AN OPTIONAL UPGRADE Jayson's core functionality is free. Browsing, editing, saving, splits, Shortcuts, and working with up to two tabs at a time cost nothing. A one-time in-app purchase enables having more than two tabs open at once, switching between light and dark themes, and personalizing the app icon, accent color and type icons. One purchase, no subscription.

JSON Scope opens the JSON files other tools give up on. A 900 MB API dump, a 2 GB export, a multi-million-line NDJSON log: JSON Scope maps the file, indexes it once, and stays interactive without loading it into memory. Everything happens on your device. JSON Scope makes no network connections, has no account and collects no data. On macOS it ships without the network entitlement, so the system itself prevents it. FREE • Open .json files up to 50 MB • A virtualised tree that expands lazily at any depth • A raw byte view with line numbers • Find keys and values, with match counts and next/previous • Precise validation: line, column, the offending token, and what was expected • Copy a node's JSONPath, its value, or its whole subtree • Quick Look previews of JSON in Finder (macOS) PRO • Open .json files of any size — tested to 2 GB — and .jsonl / .ndjson • Table view: records as rows, with inferred column types, sorting and filtering • JSONPath queries, including filters such as $.store.book[?(@.category == 'fiction')].title • jq-style queries: . .a.b .[] | select(...) {x, y} keys length map to_entries • JSON Schema (2020-12) inference for any node • Structural diff of two documents, by key and by position • Edit values and keys, then save — every byte you did not touch is preserved exactly • Export any node as JSON or CSV • A "Query JSON File" action for Shortcuts and Spotlight JSON Scope Pro is available as a monthly or yearly subscription, or as a one-time lifetime purchase.
