Microsoft Edge: In-browser JSON viewer
Improvements to how JSON files are displayed in the browser, which includes a color-coded tree view with line numbers and the ability to collapse and expand the data. This functionality will trigger automatically when the browser navigates to a JSON file on the web or the user opens a local one. Additional features and enhancements will roll out as available.
