Frequently asked questions
How many spaces become one tab?
Four consecutive spaces become a single tab — the most common convention. Odd remainders (1–3 spaces) are kept.
Is this safe for Python?
Yes, as long as you convert the whole file consistently — mixing tabs and spaces is what breaks Python.
Are strings affected?
Yes — spaces inside string literals also match. For one-off conversions that is usually fine; check the output.
