Swap Rows and Columns in a CSV
Transposing a CSV swaps its rows and columns: a file with 10 rows and 5 columns becomes 5 rows and 10 columns. It is the quickest way to flip a wide table to a tall one, or rotate a report into the orientation a chart or pivot expects — all in your browser, with no upload and no signup.
Common Use Cases
- Rotate a wide table to a tall format for easier analysis.
- Prepare data for charting tools that expect a specific orientation.
- Convert a row-per-metric format to column-per-metric.
- Fix orientation issues in exported reports before further processing.
