Frequently asked questions

What happens if there are two commas in a row, like '1,,2'?>
The empty entry between the commas is skipped entirely. Your output will contain '1' and '2' on separate lines with no blank line between them.
Does a trailing comma at the end of a line add a blank output line?>
No. Trailing commas are ignored, so '1,2,' produces just two lines — '1' and '2' — with nothing after the last value.
Can I paste multiple rows of comma-separated numbers at once?>
Yes. All input lines are processed together and flattened into one continuous line-separated list in the order they appear.
Will extra spaces around numbers be included in the output?>
No. Leading and trailing whitespace is trimmed from every value before it is written to the output, so '10 , 25 , 7' becomes clean lines of '10', '25', and '7'.
