UNFOLD YOUR DATA
A small tool for the finer details.
JSONFold brings a source editor and a navigable structure into one workspace. Format a response, follow a nested array, or jump straight to the value you need.
Local by design
The app processes editor text and imported files in your browser. It does not upload these documents or automatically store your work. We use Umami analytics, served from analytics.exaultlabs.com, to measure website visits and count button actions using fixed event names. We do not run session recording or Meta Pixel. Button events do not include document contents, clipboard text, search terms, filenames, imported URLs, field names or JSON paths. Page URL query strings and fragments are excluded from analytics. Normal visit metadata is still collected. Only your light or dark theme preference is saved in this browser. URL imports contact the address you provide. Export anything you want to keep before closing the page.
Make yourself at home
Use Ctrl/⌘ + Enter to switch between Source and Structure, Ctrl/⌘ + F to find a value while exploring, and the arrow keys to move between branches.
JSONFold is an independent tool. It is not affiliated with other JSON viewer services. Standard JavaScript number precision applies when parsing and formatting numeric values.
