How to use Reformat a Vector
- 1. Paste your vectors. Enter one vector per line, in whatever notation you currently have, for example (1, 2, 3) or 4 5 6. Mixed notations across lines are parsed the same way.
- 2. Choose the output format. Pick from Parentheses, Brackets, Braces, Space-separated, Comma-separated, or Column layout for Output format, depending on what notation your next destination expects.
- 3. Copy the converted vectors. The output pane shows every vector rewritten in your chosen format, one per line except in Column mode. Copy the result into your document or code.
When to use Reformat a Vector
Reformat a Vector converts vectors between common notations: parentheses, brackets, braces, plain space or comma separation, or a one-component-per-line column layout. Use it whenever vectors arrive in one notation but need to match another for a document or program.
- Switching from math notation to code syntax. A vector written with parentheses in a math textbook, like (1, 2, 3), needs to become bracket notation to paste directly into a Python or JavaScript array literal.
- Preparing vectors for a spreadsheet column. You have vectors written with parentheses or brackets and need each component on its own row in Column layout, ready to paste directly into a spreadsheet column.
- Matching a textbook's notation style. You are copying vectors from one source that uses braces and need them in parentheses to match the notation convention used in your own homework writeup.
- Cleaning inconsistent notation from mixed sources. A list of vectors was copied from several different tools or documents and uses inconsistent brackets and separators, and converting them all to one format makes the list uniform.
Examples

About the Reformat a Vector tool
Reformat a Vector is a free online tool that works entirely inside your web browser. Convert vector formats. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 234 Math utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with the Output format setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Reformat a Vector 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.
