Space to Tab Converter

Mixed indentation — some lines using tabs, others using spaces — is a common source of messy diffs and linter complaints when merging code from different editors or contributors. Upload a file or paste code, pick a conversion direction, and this tool standardizes every line's indentation in one pass.

Common uses

Normalizing a file before committing it to a project with a strict indentation style guide, or cleaning up code pasted from a source that used a different convention than your own editor.
