What Transpose CSV can do:

Transpose CSV flips your data matrix it turns rows into columns and columns into rows. This is useful for reorienting datasets, especially when a vertical view is better for comparison or when working with systems that require column-major formats. It handles uneven rows by padding shorter ones, so the output remains consistent. All changes happen in your browser, instantly.

Example:

Before:

Name,Age,City
Alice,30,New York
Bob,27,London

After transposing:

Name,Alice,Bob
Age,30,27
City,New York,London

Common Use Cases:

Useful for switching the layout of tabular data in spreadsheets, preparing CSVs for systems expecting a column-first orientation, or making wide datasets more readable. Great for data prep, formatting, and visualization tasks.

Useful Tools & Suggestions:

If you’re flipping rows and columns, Convert CSV to a Matrix can help visualize the shape before and after. And once it’s transposed, Rename CSV Columns can bring clarity to the new top row.
