Tabify vs. Untabify — What's the Difference?

Tabify converts multiple consecutive spaces in a text into tab characters, which can reduce the file size and often aligns columns neatly in code editors. Whereas, untabify does the opposite by converting tab characters back into spaces, which is preferred for maintaining uniformity in text editing environments.

When using tabify, developers ensure that their documents are more compact, as tabs typically consume less space than equivalent spaces. On the other hand, untabify is used to avoid issues like misalignment that occur due to different tab settings across various text editors and development environments.

Tabify is often used in environments where file size is critical, such as when working with large code bases or limited storage scenarios. Conversely, untabify is favored in collaborative settings where multiple people work on the same files, to prevent rendering issues caused by different tab interpretations.

Some coding standards specifically recommend tabifying for the neat arrangement of code blocks and data. In contrast, other standards enforce untabifying to ensure that the code looks the same on any editor, regardless of how tabs are configured.

While tabify might be more efficient in terms of storage, untabify enhances readability and consistency, which is crucial in environments like open-source projects, where developers from different backgrounds contribute to the same code base.
