What is the Add/Remove Line Numbers Tool?
The Add/Remove Line Numbers Tool is a simple yet powerful utility that allows you to automatically insert sequential numbers at the beginning of each line in a block of text, or to strip them away if they already exist. It's an essential formatting tool for anyone who needs to reference specific lines in a document, such as programmers, legal professionals, and writers.
What Problem Does This Tool Solve?
When reviewing a code snippet, a legal contract, or a long manuscript, it's often necessary to refer to specific lines (e.g., "See line 42 for the error"). Manually adding these numbers to a long document is an extremely tedious task. Conversely, if you have a block of text with line numbers (perhaps copied from a code editor) that you want to use in a report, manually deleting each number is just as time-consuming. This tool solves the problem by automating both processes, allowing you to add or remove line numbers from thousands of lines in an instant.
How to Use the Tool?
- Paste Your Text: Copy your text and paste it into the text area.
- Choose an Action:
- Click the **"Add Line Numbers"** button to prepend numbers (`1.`, `2.`, `3.`, etc.) to each line.
- Click the **"Remove Line Numbers"** button to automatically strip existing numbers from the start of each line.
- Copy the Result: The text in the box will be updated instantly. Use the "Copy Result" button to grab the formatted text.
Frequently Asked Questions (FAQ)
- 1. How does the "Remove" function work?
- It uses a regular expression to find and delete any sequence of digits followed by a period at the very beginning of each line. This is effective for most standard numbered lists.
- 2. Can I customize the number format (e.g., without a dot)?
- The current version provides a standard `1.` format for simplicity. We may add customization options in the future.
- 3. Is my text data private?
- Yes. All processing is done in your browser. Your text is never sent to our servers, ensuring your data remains completely private and secure.
