Open JSON as a visual tree, change values without losing track of brackets and commas, or edit the source directly when you want full control.
Your data stays in your browser. Files and pasted JSON are processed locally and never uploaded.

JSON is easy for software to exchange, but a large response or configuration file can be difficult to follow as plain text. The visual tree separates property names, values, objects, and arrays so you can understand the structure before changing it.
Both views stay connected. A valid source edit updates the tree, and a visual edit updates the JSON source. If the source is temporarily invalid, the last valid tree remains available while you correct it.
Objects group named properties, such as name, email, or settings. Arrays hold an ordered list of items, such as products, colors, or customer records.
JSON values have a type. A string is text in double quotes. A number is written without quotes. A boolean is either true or false. Null means a value is intentionally empty. Objects and arrays can contain any of these values and can be nested inside one another.
Keeping the correct type matters: 42 is a number, while "42" is text. The type selector lets you change that distinction deliberately.
Use the editor to inspect API responses, update configuration files, clean up exported data, find a deeply nested value, or check whether a document is valid JSON. Search can jump between matching property names and string values, while formatting and minifying give you readable or compact output.
For arrays of similarly shaped objects, bulk actions can add, rename, or remove the same property from matching records without changing unrelated objects elsewhere in the document.
