 FAQ

Why would I want to convert spaces to tabs?

Tabs can make files smaller and allow developers to customize indentation width in their editors without changing the file. Some projects specifically require tab indentation, and this tool helps you comply with those standards.
Will converting spaces to tabs break my code?

No, the conversion is purely cosmetic and won't affect code execution. However, in languages like Python where indentation is significant, you should test the code after conversion to ensure proper formatting is maintained.
Can this tool handle mixed indentation?

Yes, the tool can identify and convert different levels of space indentation to appropriate tab levels. However, it's recommended to maintain consistent indentation throughout your codebase.
What happens to spaces in the middle of lines?

The converter only transforms leading spaces used for indentation. Spaces within lines of code, such as those used for alignment or in strings, remain unchanged.
