Converted Output
Convert Tabs to Spaces (and Back)
Switch your indentation between tabs and spaces in one click. Convert tabs to a set number of spaces, or convert leading spaces back into tabs, using the tab size of your choice.
Two directions
- Tabs → Spaces: replace every tab with N spaces
- Spaces → Tabs: turn leading spaces into tabs
- Configurable tab size from 1 to 16
- Leaves non-indentation spacing intact when converting to tabs
Why it matters
Mixing tabs and spaces is a common cause of broken indentation and noisy diffs. Normalizing to one style keeps code consistent across editors and teammates.
The tabs vs. spaces debate
Both approaches are valid, but a project should pick one and stick to it. Many style guides and linters enforce a specific choice; this tool lets you convert existing files to match whichever convention your project uses.
