About this app
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, w…
App details
What you can learn from JSON Scope
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 9 screenshots above are JSON Scope's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: JSON Scope runs a light set with one background colour (#FCC44C) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #9C7C44, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
