How to use Transpose a String
- 1. Paste the multi-line string. Enter text arranged as several lines of equal or near-equal length into the input pane, forming a grid of rows and columns. Transpose a String flips that grid.
- 2. Read what the tool computes. Each character's row and column position is swapped, so the first column of the input becomes the first row of the output, exactly like transposing a matrix.
- 3. Copy the transposed grid. Copy the resulting multi-line output, now with rows and columns swapped, and paste it wherever the rotated layout is needed.
When to use Transpose a String
Transpose a String flips the rows and columns of a multi-line block of text, treating the lines as a character grid. Use it whenever text laid out in rows would be more useful read as columns, or the reverse.
- Converting a row-oriented table to columns. You pasted a small table where each line is a row of characters, but you actually need the data column-oriented for a different tool or layout. Transposing swaps the orientation directly.
- Checking a matrix-style puzzle by hand. A puzzle or cipher exercise represents a grid of letters and asks you to read it by column instead of by row. Transposing the grid lets you read the columns as new rows.
- Rotating small ASCII art. You have a small block of ASCII art or a character grid and want to see how it looks with rows and columns swapped, a quick way to rotate simple layouts.
- Verifying a rail fence or column cipher. You are working through a classic transposition cipher exercise where flipping the character grid is a step in encoding or decoding the message.

About the Transpose a String tool
Transpose a String runs as plain JavaScript in your browser tab, with no server behind it. Flip a multi-line string's rows and columns. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's String Tools section, 159 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. A worked example further down the page shows exactly what the tool produces for a real input.
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
Does Transpose a String 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.
