There is an utility called dos2unix. You can give it a try

utf-8. So you have to do a conversion from windows to utf-8. If you refer
to language specific settings (numbers, dates etc) - this is also not
supported.

release - yet. There you can specify also the language in which you want to
represent data values, numbers etc. when reading the file.

these spreadsheet time files compatible with Linux and then load them into
HDFS. For example I know that if I saved a Excel spresheet file with DOS
FORMAT, that file will work OK with Spark CSV.  Are there tools to do this
as well?
