How to use Right-align Integers
- 1. Paste your integers. Enter one integer per line, with varying digit lengths, so the tool can measure the longest one in the list.
- 2. Read how alignment works. The tool finds the widest integer in the list and pads every shorter one with leading spaces so all the digits line up on the right.
- 3. Copy the aligned column. Copy the resulting block of right-aligned integers and paste it into a monospaced text document, code comment or plain-text report.
When to use Right-align Integers
Right-align Integers pads a list of whole numbers with leading spaces so they form a neatly aligned column, matched to the longest value in the list. Use it whenever numbers of different lengths need to visually line up in plain, monospaced text.
- Formatting a plain-text report table. You are writing a report in plain text or a code comment and want a column of numbers to line up visually instead of drifting left-aligned.
- Preparing numbers for a fixed-width console output. A command-line tool or log format expects numeric values right-aligned in a fixed-width column, and you want them formatted before pasting into the source.
- Cleaning up a copied numeric list. You pasted a list of numbers from somewhere and the varying lengths make it hard to compare values at a glance. Right-align them to make the column readable.
- Building a readable markdown code block. A documentation example shows a list of numbers inside a code block and you want them aligned neatly rather than left-justified with ragged edges.

About the Right-align Integers tool
Right-align Integers runs as plain JavaScript in your browser tab, with no server behind it. Right-align integers to the width of the longest one. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Integer Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Right-align Integers free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
