Replace every run of a fixed number of spaces in your text with a tab character. Runs entirely in your browser.
Input
Number of spaces to replace each tab character with.
Output
Guides
Replace every run of a fixed number of spaces in a block of text or code with a tab character. Useful when a style guide, linter, or collaborator requires tab-based indentation instead of spaces.
How to use it
- Paste your text or code into the input box.
- Set Tab Size — the number of consecutive spaces that becomes one tab (1–8, default 4).
- Copy or download the converted result.
Only runs of exactly that many consecutive spaces are replaced — a shorter run of spaces is left as-is, and a longer run collapses one tab-width at a time from left to right.
