Tab to Space Converter

The Tab to Space Converter replaces every tab character in your text with a set number of spaces, so indentation renders identically everywhere. Tabs display at different widths in different editors, terminals and web pages, which makes shared code and formatted text look ragged. Converting tabs to spaces removes that ambiguity and guarantees your indentation appears exactly as intended.

It is built for developers following style guides that mandate spaces, writers pasting tab-indented content into systems that mishandle tabs, and anyone preparing text for a tool that expects only spaces. You simply choose how many spaces each tab should become, and the tool rewrites the whole document consistently in a single pass.

Everything runs locally in your browser using JavaScript, so nothing you paste is uploaded or stored. Set your preferred tab size, and the converted text appears instantly along with a statistics panel showing how many tabs were replaced, giving you immediate confidence that the indentation is now uniform.

Features

• Replaces every tab character with a configurable number of spaces from one to sixteen.
• Keeps all other text, including existing spaces and line breaks, exactly as it was.
• Applies the same tab width everywhere so indentation is perfectly consistent across the file.
• Works on source code, data files, config files and plain text pasted from any editor.
• Shows a stats panel counting how many tabs were converted and the tab size you chose.
• Runs instantly and offline with no account, no upload and no limit on how much you paste.
• Renders output in a monospace view so you can verify indentation lines up correctly.

How to use Tab to Space Converter

1. Paste the code or text that contains tab characters into the input box.
2. Set the tab size to the number of spaces each tab should become, such as two or four.
3. The converted text updates live as you paste or change the tab size.
4. Check the statistics panel to confirm how many tabs were replaced.
5. Copy the space-indented result or export it as a TXT file for your project.

Benefits

• Meets style guides and linters that require spaces instead of tabs for indentation.
• Makes indentation render identically in every editor, terminal, diff view and web page.
• Prevents mixed tabs and spaces that cause misaligned code and noisy version-control diffs.
• Prepares tab-separated or indented content for systems that only understand spaces.
• Keeps proprietary source code private because all conversion happens on your device.
• Gives an instant count of converted tabs so you can trust the whole file was processed.

The width a tab appears at is decided by whatever program displays the text, so the same file can look neatly aligned in one editor and badly indented in another. By expanding every tab to a fixed number of spaces, you bake the intended layout directly into the characters, which is why many language style guides and formatters prefer spaces for indentation.

Choose a tab size that matches your project convention, commonly two spaces for web code or four for many other languages. If you later need to reverse the process to reduce file size or match a tab-based standard, the companion Space to Tab Converter turns fixed-width space groups back into tab characters using the same size setting.
