About Add Line Numbers

The Add Line Numbers tool places incremental numbering at the start of each line. Use it to organize lists, label code blocks, create ordered datasets, or prepare content for documentation and reviews.

Example

Input:
Apple
Banana
Mango

Options: Start = 1, Step = 1, Separator = “. “, Pad numbers = yes (2 digits)

Output:
01. Apple
02. Banana
03. Mango

How to use it

Step 1: Paste or type your lines into the input box.
Step 2: Choose a starting number and step increment.
Step 3: Set a separator (for example “. ” or ” – “).
Step 4: (Optional) Enable padding to align numbers visually.
Step 5: Click Add Line Numbers and copy the result.

Who needs this?

This is handy for editors, developers, data entry personnel, VAs, QA reviewers, and content creators who need ordered lists or labeled items for uploads and documentation. After numbering you may want to reorder with Sort Text or add common prefixes using Add Prefix & Suffix.

Why use this tool?

Automatic numbering saves time and avoids manual mistakes when dealing with long lists. It produces consistent formatting and makes items easier to reference in reviews, emails, or spreadsheets.
