Problem with metadata file

Hi there,

My metadata.tsv file is not recognized well by Qiime. I prepared metadata in excel first, then copy it into notepad, and run this command to check:
cat $WORKING/metadata.tsv

It did not showed me a well recognized table...i mean some information are present in wrong columns.

I would like to ask if you could suggest me a command or a text editor to make a great metadata file.

Thank you very much,

Best regards,

Toan
