JSON viewer

When you open a JSON file in Polypane (either from a URL, or as a .json file on disk) it is shown in a json viewer that shows the json in a collapsible tree. The json viewer works in all panes as well as in the browse panel.

JSON tree

The JSON tree shows you the data in a formatted tree. From the top bar you can save the json file or copy the json to the clipboard.

Rich data view

Each entry has a type, like number, url, text or datetime with an associated icon and color.

For specific types we add more information, like the length for objects and arrays or a pretty-print of the date for datetime fields.

Urls show a favicon and clicking them opens them in a new tab.

Filtering

Filter your JSON file with plain text that will be matched against both the properties and values, and only show the entries that match.

Expand and collapse

Quickly expand or collapse all objects and arrays with the "Expand all" and "Collapse all" buttons.

Click the down arrow next to the expand or collapse buttons to show a list of properties that you can expand or collapse individually. This makes it easy to navigate large JSON files and see only the parts you care about without repeatedly having to expand or collapse the same data types.

Raw data view

Toggle to the raw data to see the json as it's sent by the server. Click the format button to format the raw data using JSON.stringify. The save and copy buttons will use the data as shown in this overview.
