Frequently asked questions
Why convert tabs to spaces?
Tabs render at different widths in different editors, which breaks alignment. Spaces look identical everywhere, so code and text stay consistently formatted.
How many spaces should a tab become?
4 is the most common default (Python, many style guides). 2 is popular for JavaScript and HTML, 8 matches the classic terminal tab stop. Pick whatever your project uses.
How does Spaces → Tabs work?
It converts each run of N spaces (your chosen width) at the start of a line into one tab. Spaces in the middle of a line are left alone to protect alignment.
Will this change my code's meaning?
For most languages, no — indentation is visual only. For Python and YAML, indentation is significant, so always re-run your code after converting to make sure it still works.
Is my text sent anywhere?
No. The conversion happens entirely in your browser. Your text never leaves your device.
