Add Prefix to Lines

What Is Add Prefix to Lines?

Add Prefix to Lines is a text formatting tool that places custom text at the beginning of multiple lines at once. A prefix can be a single character, a word, a phrase, a symbol, punctuation or a combination of characters.

The tool is useful whenever the same text needs to be inserted before many separate lines. Instead of editing each line manually, you can provide the prefix once and apply it consistently to an entire block of text.

Why Use Add Prefix to Lines?

Adding identical text to the beginning of many lines manually can be repetitive and prone to mistakes. This tool performs the operation consistently and provides an immediate result that can be copied into another application.

How to Use Add Prefix to Lines

Use the tool to insert the same text at the beginning of each applicable line in just a few steps.

1. Enter a prefix — Type the text, symbol, punctuation or characters you want to add at the start of each line.
2. Enter your text — Paste or type the multiline text into the input area.
3. Choose the options — Decide whether empty lines should be prefixed and whether trailing whitespace should be removed.
4. Add and copy — Click Add Prefix, review the result and use Copy Result to copy the finished text.

Add Text to the Beginning of Every Line

Adding a prefix to lines is a common text-editing task. It can be useful when formatting lists, preparing text for code or markup, adding quotation markers, inserting labels or applying a consistent identifier to a collection of lines. The YesTools Add Prefix to Lines tool automates this repetitive task by applying one custom prefix across the entire input.

For example, entering - as the prefix turns separate lines into a simple bulleted list. Entering > can add a quotation marker to each line, while entering a word such as Note: can add the same label to every line. The prefix is inserted exactly as entered, including spaces and punctuation.

Prefix Multiple Lines at Once

When a document contains many lines that need the same beginning text, manually editing every line can take unnecessary time. This tool processes the complete block at once, making it suitable for lists, notes, plain-text data and other multiline content.

Add Symbols, Spaces and Custom Text

The prefix field accepts ordinary text as well as symbols, punctuation and spaces. You are not restricted to a predefined collection of prefixes. Enter exactly what you need and the tool places it at the beginning of each applicable line.

How Prefixing Lines Works

The tool treats each line of the input independently. The chosen prefix is placed before the existing content of each applicable line. Existing line order and the text within each line are preserved.

By default, empty and whitespace-only lines are skipped so that the tool does not introduce unnecessary characters into blank areas of your text. If you want every line, including empty lines, to receive the prefix, select "Include empty lines". The optional trailing-whitespace setting removes spaces and tabs from the ends of lines before adding the prefix.
