Google tells me a cvs file is a Canvas 3 Drawing file, so I am going to assume you want a csv file (Comma seperated value). Google also tells me that to export a query as a csv file that I should do this:
Right click on your query and select export then move to Text File
In the Save File dialog you can give your file the .csv extension
Then on the export wizard screens you can choose a comma to seperate your data.
