A PRACTICAL GUIDE
Get to know your data.
A quick reference for the current release.
Start with a sample
Open the workspace and paste a JSON document, or use the built-in example. Inputs are limited to 200 KB and 40 nesting levels. Press Inspect JSON to validate and format it.
Follow the paths
Each row uses JSON Pointer notation: / is a separator, ~0 represents a tilde and ~1 represents a slash inside a key. The root is shown as (root). Search filters both paths and displayed values.
Take your output
Copy formatted JSON or download a JSON file. Export includes the complete validated document, even when the node list is filtered. Nothing is automatically saved; a page reload clears your workspace.
