Hi, I always encounter this error while uploading ads in bulk "a file must be in csv or excel format..." how does this happen? and how to resolved this error? its really annoying all the time. please help
yes, i've had the same thing. it seems like adcenter should be able to "talk" to Excel, but apparently microsoft doesn't realize that they own both. i just copy/paste, but then i don't have huge numbers of keywords to deal with either.
