About add line prefixes
Add the same prefix to every line in a multiline text block. These line-based tools are best for lists, logs, copied spreadsheet columns, prompts, and batch text edits where each line should be treated as a separate item.
Use them when you need to reshape a multiline block without manually touching every row. They are especially useful for bulk line numbering, sorting, joining, trimming, prefixing, filtering, and other list operations.
Frequently asked questions
Will it preserve my line order?
Yes. It keeps the original line order unless the selected action is meant to sort or reverse the lines.
Can I use this on hundreds of lines at once?
Yes. It is intended for bulk line operations, so it is much faster than editing long lists line by line.
What should I verify before copying the output?
Check delimiters, prefixes, suffixes, and filtered results if your text has spacing-sensitive or duplicate-looking lines. A quick review helps catch edge cases before you paste the result elsewhere.
