Builds a new matrix where output[row][column] equals source[column][row] and exports it as XLSX, CSV, TSV, or JSON.
Builds a new matrix where output[row][column] equals source[column][row] and exports it as XLSX, CSV, TSV, or JSON.
Very wide or tall data can grow substantially after transposition; the tool limits oversized sheets before allocating the new matrix.
Supported formats
Reads XLSX, XLS, CSV, and TSV in the browser. The exact output format is shown in the tool controls.
| Format | Support |
|---|---|
| XLSX / XLS | Cell data; advanced objects may not be preserved |
| CSV / TSV | UTF-8 delimited data; one table per file |
Tips for better results
- Remove unused trailing rows and columns first.
- Avoid merged cells because a plain matrix cannot preserve their layout.
- Use XLSX when the transposed result contains commas or line breaks.
FAQ
What happens to the first row when data is transposed?
The first source row becomes the first output column, including its header values.
Can I transpose CSV data into Excel?
Yes. Upload CSV, choose XLSX as the output format, and download the transposed workbook.
Are formulas adjusted like Excel Paste Special Transpose?
No. The tool transposes cell values and does not rewrite formula references.
Is there a size limit for transposing a worksheet?
The page blocks unusually large matrices to protect browser memory and responsiveness.
Does transposing modify the uploaded file?
No. A separate output file is created.
