.JSON

Introduction

Visual Studio Code keeps its settings in files named settings.json. The user settings apply everywhere and live in the user’s profile: %APPDATA%\Code\User\settings.json on Windows, ~/Library/Application Support/Code/User/settings.json on macOS and ~/.config/Code/User/settings.json on Linux. Workspace settings, in a project’s .vscode/settings.json, override them for that project and are often shared with the code.

The Settings screen in VS Code edits the same files, and the command “Open User Settings (JSON)” opens the file itself. Editors built on VS Code, such as VSCodium, use the same format in their own folders.

Structure

The file is JSON with two relaxations, which VS Code calls JSON with Comments: // and /* */ comments are allowed, and a trailing comma is tolerated. The top level is one object. Its keys are setting IDs with dotted names, such as editor.fontSize or files.autoSave, and are not nested by their dots. A key made of a language name in square brackets, such as "[python]", holds an object of settings that apply only to that language.

{
  // Editor
  "editor.fontSize": 14,
  "files.autoSave": "afterDelay",
  "[python]": {
    "editor.tabSize": 4
  }
}
