How to use Duplicate a Vector
- 1. Paste your vector. Enter one or more vectors in the input pane, one per line, written as components in parentheses. Each line will be repeated according to the setting below.
- 2. Set the number of copies. Enter a value in Copies to control how many times each input vector is repeated in the output, useful for generating repeated rows quickly.
- 3. Choose the output wrapping. Pick Parentheses, Brackets or None from the Wrap setting to control how the duplicated vector components are enclosed in the result.
- 4. Copy the duplicated list. Copy the output list, containing each input vector repeated the requested number of times, into your script or spreadsheet.
When to use Duplicate a Vector
Duplicate a Vector repeats one or more vectors a chosen number of times, producing a longer list without retyping the same line over and over. It is a small convenience tool for building test data or repeated rows.
- Building test data for a script. You need a batch of identical vectors to feed into a script that processes a list, and duplicating one vector ten times quickly generates the test input.
- Seeding an initial condition across multiple entities. A simulation needs several objects to start at the same position, and duplicating the initial position vector produces the correct number of starting rows to paste in.
- Filling a placeholder dataset. You are prototyping a spreadsheet or form and need repeated rows of the same vector as a placeholder before real data is available.
- Creating a baseline for comparison. You want several identical copies of a reference vector so you can manually apply different transformations to each one and compare the results side by side.

About the Duplicate a Vector tool
Duplicate a Vector does its work locally, right in the browser. Create copies. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Math Tools collection on EditSafely, a set of 234 small, focused Math utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Copies and Wrap, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does Duplicate a Vector cost anything?
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?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
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?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
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.
