Common Mistakes to Avoid

⚠️

Wrong number of spaces per tab

Solution: Common settings: 2, 4, or 8 spaces. Match your editor/project settings.

⚠️

Tabs in string literals changed

Solution: Tabs in strings get converted too. May change program behavior if tab char matters.

⚠️

File becomes much larger

Solution: Converting each tab to multiple spaces increases file size. Usually minimal impact.
