Add Prefix or Suffix to Every Line of Text

If you ever search for "add prefix to multiple lines," "bulk add bullet points," or "wrap text in quotes," this tool is made for you. Paste any block of text, choose the prefix and/or suffix you want, and instantly reformat each line without writing scripts or regex.

Why This Tool Saves Time

  • Content creators can convert plain interview notes into Markdown quotes or bullet lists in one click.
  • Developers quickly add // comments, HTML tags, or array syntax to multiple lines.
  • Data professionals wrap CSV values with quotes or delimiters before importing into spreadsheets.

How It Works

  1. Paste or type your text into the left pane.
  2. Provide a prefix (e.g., - , > , const ) and/or suffix (e.g., ;, </li>).
  3. Enable "Skip empty lines" to avoid adding characters to blank rows.
  4. Use built-in templates for common patterns like Markdown bullets, blockquotes, HTML lists, or code comments.
  5. Copy the formatted results or download them as a .txt file.

Power Tips

  • Combine with Split a String or Batch Text Replacer to prep data before adding prefixes.
  • Use suffixes to close syntax structures (e.g., ", for JSON arrays or </li> for HTML lists).
  • Keep prefixes short for accessibility—screen readers interpret long repeated prefixes as noise.

Frequently Asked Questions

Can I remove prefixes instead?
Yes. Set the prefix field to blank and use the Batch Text Replacer tool afterward to strip unwanted characters.

Does it handle large lists?
The tool runs in your browser and handles thousands of lines instantly without uploading your text.

Will whitespace be preserved?
Existing indentation stays intact; we simply prepend or append your custom characters to each line.
