Uncover edge cases

Sometimes a field can be null, have an unexpected value or be missing entirely. View any field's related values and see what to expect when you least expect it. Or check out the inferred JSON schema to see what your JSON is really made of.

Quickly search your whole JSON file

Search for absolutely anything in your JSON file with blistering speed. Use the fuzzy matching and keyboard shortcuts to make navigating your files even faster.

Collaborate with the whole world (and yourself)

Easily share your JSON documents with any distant relative. Link right to the part of the document you're on. Or save the link for some casual browsing later in the evening while enjoying a glass of red.

And lots more features…
