Swap rows and columns in a CSV — what was a row becomes a column. Useful for converting wide-format spreadsheets to long-format, flipping summary tables, or reshaping pivot-style data for charting tools that expect rows of metrics.
Free is enough for most one-off jobs. Pro raises the file and batch caps; Pro + Media unlocks GB-scale streaming and unlimited duration.
Larger files supported on Developer (5 GB CSV) and Enterprise (unlimited). All processing happens in your browser — files never reach a server.

On Pro yes (100k row limit). The result will have 100k columns, which most spreadsheet tools handle poorly — use a database or scripting language for very wide outputs.
The transposer pads to the widest row, so missing cells become empty in the transposed output.
