Errors in CSV list upload

[Anonymous]

I uploaded a CSV list, and some of the telephone numbers got incorrectly matched to the wrong leads. Has this happened before to anyone?

Emma,

Were there blank rows or columns in your Excel file? I know having those can throw Marketo off during an upload.

These were all new contacts so there was nothing to overwrite, and I'm pretty sure it was properly lined up in the CSV. I just converted it from an excel - is there a trick or procedure I need to do to make that work?

Was the list properly lined up in the CSV? Did the list overwrite existing phone #?

You can just go back to the list and create two columns:

Email | Phone and then overwrite the problems.
