Delimiter is not detected rightly

I have a file with no header that contains this data structure

column ; comlumn2,comlumn2,comlumn2,

column ; comlumn2,comlumn2,comlumn2,

column ; comlumn2

here the delimiter is ; but the library is detecting ,

Is the last line there is no , so why the library still detect , ?

Any solution ?

If I add a header how to tell library to detect delimiter only on header.

I found same case here but I don’t have header and last line does not contain ,

Again, , seems to be the “better” delimiter here as it produces more fields (which is probably desired in 90% of all cases).

You can set the delimiter directly when parsing or only use the first x lines of the data as I described here: https://github.com/mholt/PapaParse/issues/861#issuecomment-860084246

I do not think we should complicate more the guessing and we should assume that is not perfect (specially when mixing delimiters on data). There is already an option to specify the delimiters to guess (and its a sorted list allowing to prefer ; over ,). You should use if required.

I’m closing this issues as there is nothing else to do from our side. If yo do not agree, please provide some simple solution for your case.

Thanks!
