How to Add a Prefix or Suffix to Every Line of Text
Adding the same text to the beginning or end of multiple lines is a task developers, writers, and spreadsheet users face constantly. This free tool does it instantly — just paste your text, type your prefix or suffix, and the result is ready.
Paste your list of words, URLs, file names, or any multi-line text into the Input Text box.
Enter the text you want before each line in the Prefix field. For example, type " to add a quote mark to the start.
