A true CSV transpose
The parser understands commas inside double-quoted fields, escaped quotes, embedded line breaks, and empty cells. The output writes each original row across a new row, preserving the order of values.
Uneven rows are padded safely
When rows contain different numbers of fields, shorter rows receive empty cells so every transposed row has the same width. Fields are quoted again whenever the output needs it.
Private browser processing
Parsing, transposing, copying, and downloading happen locally in this browser. Input is limited to 10 MB and malformed unclosed quotes are reported.
常见问题
你可能还想知道
Can quoted CSV fields contain commas or line breaks?
Yes. Double-quoted fields may contain commas, line breaks, and escaped double quotes.
What happens when rows have different lengths?
Missing cells are treated as empty values so the transposed output remains rectangular.
Does this upload my CSV?
No. The conversion runs entirely in your browser.
Can I transpose a CSV with a header row?
Yes. The header is treated like any other row and becomes the first output column.
