csvclean: performance issue detecting errors

Created by: ThomasMic

Hello,

we faced a problem with csvclean on a simple case of error :

• the header of the file is composed of n columns
• the rest of the file is a great number of lines with n+1 columns

while validating this kind of file with found that csvclean is taking more and more time, not in a linear scale, to report errors that it found on each line

Thanks
