📖 What is Tab to Spaces Converter?

The Tab to Spaces Converter replaces tab characters with a specified number of spaces, or converts spaces back to tabs. It supports simple replacement and alignment-preserving modes, helping code maintain consistent indentation across different editors.

Core Features

How to Use

  1. Paste Text: Paste tab-containing text or drag a file into the input area.
  2. Set Width: Set the number of spaces per tab (default 4).
  3. Choose Mode: Simple replace or alignment-preserving mode.
  4. Direction: Choose Tab→Spaces or Spaces→Tab.
  5. Copy/Download: Copy results to clipboard or download as a file.

Use Cases

Code Standardization

Unify tabs to spaces in team projects, ensuring consistent indentation across editors and avoiding format conflicts in code reviews.

Config File Processing

YAML and other config files require space indentation. Convert tab-indented YAML to spaces to avoid parsing errors.

Document Formatting

Convert tab-aligned tables to space-aligned text for correct display in Markdown, plain text emails, and other contexts.

Reverse Conversion

Convert space indentation back to tabs to reduce file size and minimize diff noise in Git repositories.

Background Knowledge

The tabs vs. spaces debate is a classic programming topic. Tab advantages: one character per indent level, smaller files, personalizable display width. Space advantages: consistent display regardless of editor settings. Most modern style guides (Google, PEP8, Airbnb) recommend spaces. Tools like EditorConfig and Prettier can automatically unify indentation styles.

FAQ

Why convert tabs to spaces?

Different editors interpret tab width differently, causing inconsistent indentation. Spaces ensure consistent display everywhere.

What tab width should I use?

Most common: 4 spaces (most languages) and 2 spaces (HTML/CSS/JS/Go). Python PEP8: 4; Google frontend: 2.

What is alignment preservation?

Considers characters before each tab, replacing with the right spaces to align to the next tab stop position.

Does it support reverse conversion?

Yes. Switch direction to convert consecutive leading spaces back to tabs.

Result looks wrong?

Check tab width setting. Alignment mode works best for indentation, not table alignment. Try different widths.
