About Tab Space Converter

The Tab-Space Converter is a browser-based utility that lets you easily convert between tab characters and spaces in any text. In programming, differences in indentation style (tabs vs. spaces) frequently cause issues in team development.

Tab-to-spaces conversion replaces each tab with a specified number of spaces, while spaces-to-tabs conversion replaces groups of consecutive spaces with tab characters. It supports indent widths of 2, 4, and 8 spaces, covering all major coding conventions (PEP 8, Google Style Guide, etc.).

With real-time preview you can immediately see the conversion result, and it efficiently handles large volumes of code. This tool lets you instantly unify the indentation of existing code.
