Structly
A native JSON viewer for iPhone, iPad and Mac — with a Safari extension that formats every JSON page.
Open JSON from Safari, Files, Mail or the clipboard. Browse it as a tree, a sortable table or formatted source, search every key and value, and export it the way you need.
What you get
Tree, table and source
Syntax colors, counts and indentation guides make any JSON easy to read. Lists of objects, like API results, become tables you can sort by any column.
Search that finds everything
Every matching key and value is highlighted, or show only the matches. Type a path such as $.orders[0] to jump straight to it.
Understands your values
The inspector shows Unix timestamps and ISO dates as readable dates, decodes URL and Base64 strings, and opens links.
Export your way
Copy or save with 2 or 4 spaces, tabs or minified, with keys sorted if you like. Numbers keep their exact digits.
Wherever JSON shows up
The Safari extension formats JSON pages the moment they open and can send them to the app. “View in Structly” in the share sheet opens JSON from Files, Mail and other apps.
Fast and private
Multi-megabyte files open in seconds, and large pages in Safari appear instantly in a paged view. Everything stays on your device.
Privacy by default
No accounts, no analytics, no third-party SDKs, no servers. Your JSON is read and formatted on your device and never uploaded. Recent documents stay on the device where you opened them, and you can turn them off.
