Question 1

What is JSON path notation?

Accepted Answer

JSON path notation describes the location of a value in a JSON structure. Dot notation uses dots for object keys ($.user.name) and brackets for arrays ($.posts[0]). Bracket notation wraps all keys in brackets ($["user"]["name"]).

Question 2

How do I use a JSON path in code?

Accepted Answer

In JavaScript, convert dot notation to property access: data.user.name. For bracket notation: data["user"]["name"]. For arrays: data.posts[0].title. Many languages have JSON path libraries for querying complex structures.

Question 3

Can I search for specific keys?

Accepted Answer

Yes. Use the search field above the tree to filter nodes by key name. This is helpful for navigating large JSON files where you know the key name but not its location in the structure.

Question 4

Is there a limit to JSON size?

Accepted Answer

The tool runs in your browser, so the practical limit depends on your device memory. It handles files up to several megabytes comfortably. For very large files (100MB+), use a command-line tool like jq.
