Cannot Edit Default VSCode JSON Settings

The default settings in vscode is a non-editable document. It acts as a way for you to view the default settings for native settings as well as extension default settings.

These defaults are also used to identify when a setting has changed with a 'blue' line indicator, when using the settings editor:

Changes to settings are reloaded by VS Code as you change them. Modified settings are now indicated with a blue line similar to modified lines in the editor. The gear icon opens a context menu with options to reset the setting to its default value as well as copy setting as JSON.

Currently, vscode only offers 2 editable settings:

VS Code provides two different scopes for settings:

• User Settings - Settings that apply globally to any instance of VS Code you open.
• Workspace Settings - Settings stored inside your workspace and only apply when the workspace is opened.

Workspace settings override user settings. Workspace settings are specific to a project and can be shared across developers on a project.

Note: A VS Code "workspace" is usually just your project root folder. Workspace settings as well as debugging and task configurations are stored at the root in a .vscode folder. You can also have more than one root folder in a VS Code workspace through a feature called Multi-root workspaces.

You can configure these settings with the settings editor, as pictured above, or you can navigate to their JSON counterparts for manual entry (example pictured on the right below).

For workspace settings JSON, the JSON file is located in a folder of the root directory called .vscode, you can create it yourself if it is not there.

By default, VS Code shows the Settings editor, but you can still edit the underlying settings.json file by using the Open Settings (JSON) command from your command palette or by changing your default settings editor with the workbench.settings.editor setting.

Settings

You can define which view is shown using the following settings:

• workbench.settings.openDefaultSettings

  Opens the default settings any time you open regular settings (this only works with the JSON settings editor option)

• workbench.settings.editor

  Determine which editor to use, you can elect UI or JSON

• workbench.settings.useSplitJSON

  This will open a JSON settings editor, with the default settings to the left, but the default editor to the left will behave like a UI editor in that you can collapse regions based on category and there is a search input box and it will share the same tab as the json editor on the right, whereas the workbench.settings.openDefaultSettings option mentioned above puts each setting view in its own respective tab (editor)

I had the same problem and the solution that worked is below. It is true that default settings cannot be modified but the below steps explained how to edit settings in JSON:

1. Cmd+Shift+P and select Open Settings UI (Ctrl+Shift+P for Windows I think)
2. Search by entering "Settings and under menu Workbench Settings Editor and change from ui to json
3. Search for “use split JSON” and tick “Controls whether to use split JSON…”.
