What does transposing mean?
The first row becomes the first column, the second row becomes the second column, and so on — rows and columns are swapped.
Does it handle non-square data?
Yes — the tool handles CSV files where the number of rows and columns differ.
Is the header row treated specially?
After transposing, what was the first column becomes the header row.
When would I need to transpose a CSV?
When data arrives oriented the wrong way for your analysis — for example, time periods as rows that should be columns.
Is there a size limit?
Processing is local — very large files may be slow on low-memory devices.
Free. Instant. No sign-in. Open it and get the job done.
