How to use this text tool

  • Paste text that contains tab characters.
  • Choose leading-only or all-tab conversion.
  • Set spaces per tab.
  • Run the converter and verify remaining tab count.

What this tool does

This converter turns tab-based indentation into space-based indentation for consistent display across editors and code review tools.

Count tab characters, replace them with the selected number of spaces according to scope, then report changed lines and remaining tab characters.

For column-aligned text, leading-only mode is safer because it avoids changing internal table spacing.

Example

Sample input is included in the text box. Run the tool to see the processed output and the before/after statistics.

Use cases

  • Clean pasted code before review.
  • Normalize formatting before committing files.
  • Prepare text for editors, terminals, documentation, or data exchange.
  • Compare before and after structure using the result metrics.

Tips for better output

  • Use 4 spaces unless your project style says otherwise.
  • Use leading-only mode for code indentation.
  • Use all-tabs mode for plain text cleanup.

Processing details

The tool runs in the browser and focuses on safe whitespace, indentation, wrapping, line ending, or column formatting depending on the selected tool.

For critical code or regulated data, validate the final output with your project-specific parser, compiler, linter, or test suite.

FAQ

How many spaces equal one tab in code?

Common choices are 2, 4, or 8 spaces, but the correct width depends on your project or editor settings.

Should I convert all tabs or only leading tabs?

Convert leading tabs for code indentation. Convert all tabs only when you want to remove every tab character from plain text.

Can tabs inside text remain unchanged?

Yes. Leading-only mode converts indentation tabs while preserving tabs that appear later in a line.

Why do tabs look different in different editors?

Editors can display one tab as 2, 4, 8, or another number of columns, so visual alignment can change.

Does converting tabs to spaces affect code?

For most languages it does not change behavior, but indentation-sensitive languages should still be reviewed after conversion.
