  2. View your results — Dimensions appear instantly, including file size.
  3. Copy or save — Copy the results to your clipboard (tab-separated for Excel) or save as a CSV file.

FAQ

3 questions
Does this tool upload my data?
No. It runs entirely in your browser using JavaScript. Your CSV data is never sent to a server.
How is the file size calculated?
The file size is calculated from the raw text content of your CSV, measured in bytes and displayed as B, KB, or MB.
Does the row count include the header?
No. When 'Header row present' is checked, the header row is excluded from the row count.
