Which numbering styles are recognized?

Leading digits followed by a period, colon, or closing parenthesis, with or without a trailing space, such as '1. ', '1:', or '1)'.

What happens to a line without a number prefix?

It's left unchanged, since the pattern only matches and removes a prefix when one is actually present at the start of the line.

Does it remove numbers that appear later in a line?

No, only a numbering pattern found at the very start of a line is removed; numbers appearing elsewhere in the line content are left alone.

Overview

Introduction

Pasting a numbered list from a document, chat, or PDF into another tool usually means stripping the leading numbers back out first, a fiddly manual edit across many lines.

It runs entirely client-side, so nothing you paste is ever uploaded to a server.

What Is Line Number Remover?

A cleanup tool that strips a leading line-number marker, like '1. ', '1:', or '1)', from the start of every line, leaving lines that never had one untouched.

It runs entirely client-side as part of this site's String Tools collection, so nothing you paste is ever uploaded to a server.

How Line Number Remover Works

Each line is tested against a pattern matching optional leading whitespace, one or more digits, then a period, colon, or closing parenthesis, plus an optional trailing space.

Where the pattern matches, that leading portion is removed via `replace()`; lines that don't match are passed through unchanged.

When To Use Line Number Remover

Use it to turn a numbered list copied from a document or chat back into plain lines, or to clean up line-numbered code before pasting it elsewhere.

It's a fast way to get the answer without opening a code editor, a REPL, or writing a one-off script just to check.

Often used alongside Line Number Adder and Line Counter.

Features

Advantages

Recognizes several common numbering styles ('.', ':', ')') in one pass.
Leaves lines without a numbering prefix completely unchanged.

Limitations

Only strips a numbering pattern found at the very start of a line, not numbers appearing mid-line.
Doesn't verify the numbers are sequential; it removes any line-leading digit-plus-punctuation pattern regardless of order.

Examples

Stripping numbers from a pasted list

Input

1. apple
2. banana
3. cherry

Output

apple
banana
cherry

Each line's leading '<number>. ' marker is removed, leaving the plain list items.

Best Practices & Notes

Best Practices

Use Line Number Adder afterward if you want to re-number the cleaned list with a different separator style.

Developer Notes

The pattern is `/^\s*\d+\s*[.):]\s?/`, applied per line via `replace()`; it matches optional leading whitespace, digits, optional whitespace, one of '.', ')', or ':', and an optional single trailing space, without a global flag since only the line-leading match should ever be removed.

Line Number Remover Use Cases

Cleaning a numbered list copied from a document or chat before reprocessing it
Stripping line numbers from a pasted code snippet
Normalizing lines from sources that number inconsistently

Common Mistakes

Expecting numbers appearing mid-line, not just at the start, to be removed.
Assuming an unsupported numbering style, like Roman numerals, will be recognized.

Tips

If your source uses a numbering style outside '.', ':', or ')', use Find and Replace with a custom pattern instead.
