What is a Prefix/Suffix Tool?
A prefix/suffix tool adds custom text to the beginning (prefix) or end (suffix) of every line in your text. It's a simple operation with wide applications—from formatting bullet lists to preparing data for import into other systems.
- Writers formatting bullet lists and outlines
- Developers preparing array or list syntax in code
- Data analysts wrapping data for CSV or SQL import
- Marketers formatting email lists for campaigns
- Content managers adding consistent formatting to text blocks
Adding the same prefix or suffix to every line converts ordinary text into structured, formatted content ready for its intended use. Use our case converter to standardize text case before adding prefixes, or the slug generator to create URL-friendly versions.

Best Practices for Adding Prefix/Suffix
1. Consider Trailing Separators
If adding a suffix like a comma, remember the last line usually shouldn't have one. Remove the trailing comma from the last line after processing.
2. Use Both Fields for Complex Formatting
Many formatting tasks require both prefix and suffix. HTML tags, parentheses, and quoting all benefit from using both fields together.
3. Test on a Small Sample First
Before processing a large list, test your prefix/suffix on 3-5 lines to make sure the formatting is what you expect.
4. Combine with Other Tools
Use line numbering before adding prefix/suffix if you need numbered items. Use remove empty lines first if you don't want blank lines processed.
5. Keep Original If You Might Need It
After adding prefix/suffix, it's not reversible. Keep a copy of the original text in another window.
