How to Use Convert Tabs to Spaces

Converting tabs to spaces is usually done in an editor or with a script. The Convert Tabs to Spaces tool does it in the browser: paste text containing tabs, choose how many spaces per tab (2, 4, or 8), and get consistent spaces—no sign-up and no data sent to a server.

What is Convert Tabs to Spaces?

Convert Tabs to Spaces is a free online tool that replaces each tab character with a fixed number of spaces (2, 4, or 8). Useful for consistent indentation and alignment in code or configs. It is used when your style guide or tool expects spaces for indentation, or to normalize mixed tabs and spaces in a file. All processing runs in your browser; there is no upload, no storage, and no account required.

Key Features

• Every tab — All tab characters are replaced. The rest of the text is unchanged.
• Configurable width — Choose 2, 4, or 8 spaces per tab. Each tab becomes that many spaces.
• Any input — Paste or type any text containing tab characters. No size limit for in-browser processing.
• Instant result — Paste, set spaces-per-tab, and see the result. Copy when ready.
• Privacy-first — All processing happens in your browser. Your text is never sent to any server.
• No account — Use as often as you need without sign-up.

How to Use Convert Tabs to Spaces

1. Open the Convert Tabs to Spaces tool.
2. Paste or type your text (with tab characters).
3. Choose how many spaces per tab (2, 4, or 8).
4. View the result with tabs replaced by spaces. Copy the result.
5. Paste into your editor or config. Use the "Use tool" button on the docs page if you are reading this from the documentation.

Real Use Cases

• Style guide — Your project uses spaces for indentation; convert tab-indented code to spaces.
• Normalize mixed tabs and spaces — Replace all tabs with spaces so the file uses one indent style.
• Tool compatibility — Some tools or parsers expect spaces; convert tabs so alignment is explicit.
• Code migration — Convert tab-indented files to space-indented for a new codebase or CI check.
• Config and data — YAML, JSON, or config that uses tabs; convert to spaces for consistency.
• Paste from another source — Content has tabs; convert to spaces before saving or committing.

Why Use Convert Tabs to Spaces Instead of Alternatives?

• vs. Editor find-and-replace — Works in any browser. No need to open an IDE.
• vs. Manual replacement — No need to replace each tab by hand. Set width once, copy.
• vs. Spaces to Tabs — That tool does the opposite (spaces → tabs). Use this when you need tabs → spaces.
• vs. Doing nothing — Consistent space indentation avoids tab-width confusion and matches space-based style guides.

Tabs are replaced by a fixed number of spaces. If the original file used a different tab width, alignment may shift; choose the width that matches the source.

Benefits for Developers and Content Editors

• Developers — Quick conversion of tab-indented code to spaces. No one-off script.
• Content editors — Normalize indented content to spaces when the target expects them.

Common Mistakes

• Alignment looks wrong — Tabs are replaced by a fixed number of spaces. If the original was viewed with a different tab width, alignment may shift. Choose the width (2, 4, or 8) that matches the source.
• Expecting leading spaces to become tabs — This tool only converts tabs to spaces. For spaces → tabs use Convert Spaces to Tabs.
• Wrong width — Use the same width as the source (e.g. 4 spaces per tab for 4-space indent). Wrong width shifts columns.
• Forgetting to copy — The result is not saved. Copy before closing the tab or refreshing.
