Add Prefix / Suffix to Lines
Enter a prefix, suffix, or both, then paste your text. Each line is updated live. Option to skip blank lines. Great for building SQL IN lists, CSS class names, or bash command batches. Runs in your browser.
Add the same prefix, suffix, or both to every line of text. The output updates immediately and can preserve empty lines unchanged or decorate them too, depending on the Skip empty lines option.
How to add a prefix or suffix to each line
- Paste or type one or more lines of text.
- Enter the prefix to place before each line, the suffix to place after it, or both.
- Leave Skip empty lines enabled if blank lines should remain untouched.
- Review the live output.
- Copy the transformed text when ready.
How line transformation works
The tool splits the input at newline characters and processes each line independently. For normal lines, the result is simply prefix + original line + suffix, so existing spaces inside the line are preserved.
When Skip empty lines is enabled, a line whose trimmed content is empty is returned unchanged. When it is disabled, even blank or whitespace-only lines receive the chosen prefix and suffix.
Privacy and limitations
The transformation runs entirely in the browser and the text is not intentionally uploaded. The tool applies one identical prefix and suffix to every processed line; it does not number lines, parse CSV columns, interpret escape sequences, or apply conditional rules based on line content.
