FAQ
What is CSV transpose?
CSV transpose swaps rows and columns. The first row becomes the first column and vice versa. This is commonly used in data analysis to change the data view orientation.
Does transposing change the data format?
No. Transposing only changes row/column positions, not data content. Delimiters remain the same, and quoted fields are handled correctly with proper escaping.
What delimiters are supported?
Comma (,), Tab, Semicolon (;), and Pipe (|). European regions commonly use semicolons as CSV delimiters.
What if rows have different column counts?
The tool automatically fills missing cells with empty strings to ensure the transposed matrix is regular (all rows and columns have consistent sizes).
Is my data uploaded to a server?
No. Everything runs locally: Delimiter and Header are processed on your device, never sent to a server. CSV data is never uploaded to any server.
