Tab to Space Converter — Unify Your Indentation Style

When different teams use different conventions, mixed tabs and spaces in code lead to messy diffs and broken alignment. This tool recognizes only the indentation at the start of each line and accurately converts tabs to spaces, or spaces to tabs.

Tabs or spaces inside strings or code content are left completely untouched, so your code's actual behavior is never affected. When converting spaces to tabs, only full groups of your chosen width become a tab — any remaining spaces stay as spaces.

Frequently Asked Questions

Does it change tabs/spaces mid-line?

No — only the indentation at the start of each line is converted; content in the middle is untouched.

What happens to leftover spaces?

Only full groups matching your chosen width become tabs; any remainder stays as spaces.

When should I use this?

Merging code from a different team convention, or cleaning up files with mixed tabs and spaces.
