Visual Studio Code – How to use spaces by default instead of tabs

Workspace-Specific settings (VS Code)

Check if you have .vscode/settings.json in your project folder.

.vscode/settings.json file:

{
  "editor.insertSpaces": true,
  "editor.tabSize": 3
}

.editorconfig file

This file can exist at the root of your project (for project-specific settings) or in your user’s home directory (for user-wide preferences).
This can override any editor-specific settings and enforce consistent indentation rules across all supported editors and IDEs.

.editorconfig file:

# .editorconfig
root = true

[*]
indent_style = space
indent_size = 3
