Free Online Data Transpose Tool

1. Paste your CSV or TSV data into the input box.
2. Select the matching delimiter — comma for CSV, tab for TSV.
3. The transposed table is generated instantly.
4. Confirm that former rows now read as columns.
5. Copy the result for use in a spreadsheet or import.

Transposing a table swaps its two axes: the value at row r, column c moves to row c, column r. It is the same operation as Paste Special, Transpose in a spreadsheet, and it is the fix when data arrives in the wrong orientation — say, with dates running across the top as columns when you need them down the side as a single column for charting or analysis.

This tool parses your data with a delimiter you choose (comma for CSV or tab for TSV), then rebuilds it transposed. Rows shorter than the widest row are padded with empty cells first, so the output stays a clean rectangle even when the input was ragged. Fields containing the delimiter, quotes, or line breaks are re-quoted in the output following RFC 4180, so the transposed file is valid and re-importable.

Common uses include rotating a time series, reshaping a survey export, or turning a wide summary into a tall one for a database load. The transformation happens entirely in your browser, so the data never leaves your device.
