How to use this text tool

  • Paste text with repeated spaces.
  • Set how many spaces should become one tab.
  • Choose leading-only mode for code.
  • Run the converter and check alignment warnings.

What this tool does

This tool compresses space-based indentation into tab-based indentation where the number of leading spaces matches your selected tab width.

Scan leading spaces or repeated space chunks, replace complete groups with tab characters, preserve leftover spaces, and report savings.

Tabs may display differently across editors. Confirm the expected tab width before sharing output.

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 leading-only mode for source code.
  • Keep leftover spaces when indentation is not a perfect multiple.
  • Avoid tabs in alignment-sensitive tables unless required.

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 do I replace spaces with tabs online?

Paste the text, set the number of spaces per tab, and run the converter to replace matching space groups.

Will alignment change after converting spaces to tabs?

It can change if the receiving editor uses a different tab width, so review output in the target environment.

What tab width should I use when converting spaces?

Use the width used by your project, commonly 2, 4, or 8 columns.

Can partial spaces remain after conversion?

Yes. If a line has a number of leading spaces that is not divisible by the tab width, the remainder is preserved as spaces.

Why does my editor display converted tabs differently?

Tab display width is an editor setting, so the same tab character can appear wider or narrower in different tools.
