Common Use Cases
Meeting tab-required formats
Makefiles require real tab indentation — convert space-indented recipes so make stops throwing missing-separator errors.
Matching team style
Convert space-indented code to tabs before contributing to a repo whose style guide mandates tab indentation.
Shrinking indentation size
Replace 4-space runs with single tab characters to compact deeply nested files.
Frequently Asked Questions
- How many spaces convert to one tab?
- Every run of exactly 4 spaces becomes one tab character — the most common indentation width. Code indented with 2-space levels will convert every two levels into one tab.
- Why convert indentation to tabs at all?
- Tabs let each developer choose their own display width, produce smaller files, and are required by some formats like Makefiles, where recipe lines must start with a real tab character.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
