About the Tabs to Spaces Converter
Tabs to Spaces Converter replaces every tab character in your text with a set number of spaces, giving you consistent indentation across editors and platforms. Choose 2, 4, 8 or any custom number of spaces per tab and see the result immediately.
It is aimed at developers cleaning up source code, writers pasting from spreadsheets, and anyone fixing mixed indentation. Convert only leading tabs to keep tab characters inside your content intact, or convert every tab in the text.
The conversion runs entirely in your browser — your code and text are never uploaded. That keeps proprietary source private and lets the tool work offline whenever you need it.
Frequently asked questions
How many spaces should a tab be?
It depends on your style guide — 2 and 4 spaces are the most common. Set the value you need and every tab is expanded to match.
Can I convert only the indentation?
Yes. Enable “Leading tabs only” and just the tabs at the start of each line are converted, leaving any tabs inside the text alone.
Does it change my line breaks?
No. Only tab characters are replaced. Your line breaks, spaces and other content stay exactly as they were.
Is my code uploaded to a server?
No. The conversion runs entirely in your browser, so your code stays private and the tool works offline.
