What is add text to each line online?

Add text to each line online is a text utility that prepends or appends content to every row in a multi-line block. Paste lines, add a prefix like a line number, add a suffix like a comma, and copy the result. People also search for add text to text, prepend lines, append text, or type on multiple lines; this page serves that intent with %N% and %L% placeholders. It does not edit Word documents or insert HTML line breaks.

Line prefix and suffix features

Tools for append and prepend workflows.

  1. Instant updates: New text refreshes as you paste, edit templates, or change line counting.
  2. Prefix each line: Add constant text or numbered labels at the start of every row.
  3. Suffix each line: Append commas, spaces, quotes, or custom text at the end of each line.
  4. %N% line numbers: Insert auto-incrementing numbers with four counting styles.
  5. %L% line content: Repeat the original line inside your prefix or suffix template.
  6. Copy and download: Export the updated block as plain text in one click.

How to add text to every line

Three steps for prepend or append output.

  1. Paste your lines: Enter one item per line in Original text.
  2. Set prefix or suffix: Enable beginning or end text, then use %N% or %L% if needed.
  3. Copy or export: Use Copy all, Download text, or Open in new tab.

Tips for prefix and suffix templates

Avoid common mistakes when you add text to lines.

  1. One item per line: Line breaks define rows before prefix or suffix is applied.
  2. Start with %N%. : A numbered prefix is the fastest way to build ordered lists.
  3. Use suffix for delimiters: Append commas or spaces when preparing concat-style output.
  4. Pick padding early: Choose 00 or 01 modes when filenames or IDs need fixed width.
  5. Download long outputs: Text export is safer than clipboard for very large lists.

When to prepend or append lines

Common add-text-to-text tasks.

  1. Numbered lists: Prefix rows with 1. 2. 3. or zero-padded indexes.
  2. Quote wrapping: Add opening and closing characters on each line for code or CSV prep.
  3. Delimiter suffixes: Append commas or spaces when building concatenated output.
  4. Bulk labeling: Insert the same tag before many lines in logs or inventories.
  5. Template expansion: Combine %L% with fixed text to repeat line content in a pattern.
