in reply to How to change the delimiter of CSV file

you don't show us any code , we can only guess!

Somewhere in your source you specified "\t" as delimiter, change it to ",".

And please format your postings:

Use: <p> text here (a paragraph) </p> and: <code> code here </code> to format your post!
