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.
