Question

Format_Invalid when importing csv file of attendees in zoom webinar

Hi all

I have hosted webinars using the zoom platform for a couple of years with no issues.
This week I hosted the first session of 2024 - I am on the Pro profile.
When I attempted to import attendee emails and names into zoom, I received an error message saying format_invalid, described as rows. I am using the template that zoom supply for importing attendees.
I have tried creating and saving the csv file in both numbers (Mac) and Excel with the same result.

I am using a Macbook Air. Not sure of zoom version but believe it is up to date.
If it makes a difference, I now live in France having recently moved from the UK.
I have sent 2 tickets into zoom support without an answer. The last one was TS0536661.
I tried sending myself a test confirmation email, and then used that content to send out an email to all the attendees.
Some attendees were able to access the live webinar as a result, and many were not - they were asked by zoom to register, and then received a message saying their registration was pending.
Any suggestions for a resolution would be warmly welcomed.

    Hello,

     

    With Zoom Webinars registration, registrants can be imported by CSV upload and automatically approved. Once they have successfully been imported, a confirmation email will be sent to the registrants. 

     

    Reasons you may have an issue;

     

    • The CSV file can only be up to 2MB.
    • Can only upload registrants to single-occurrence(non-recurring) webinars.
    • If charging a registration fee through Paypal is enabled for the webinar, this option will not be available.
    • If your registration has additional required questions, imported registrants will be redirected to the registration page to complete the missing required questions. 
    • Bad formatting

    Is your webinar a single occurrence or a recurring series ?

    Hi Frank, and thanks for your reply.
    Here are my answers to the points you noted:

    • The csv file is 4 kb
    • It is a single occurrence webinar
    • No registration fees have been charged through PayPal or any other platform
    • I didn't use the registration process on zoom - i used a separate platform for registration and then exported the data into a csv file that I then attempted to upload to zoom
    • I wondered about formatting - I have used the same process for the last 3 or 4 years without any previous issues. I also tried using the zoom template directly and that still came up with the same error message.
      I think it must be in this area, yet don't know exactly why it is happening?

    Thank you, I do appreciate your thoughts.
    Cheers

    Terry

      Hi Terry, wondering if you had any luck solving this issue?

      I have experienced the same problem when I held my first Zoom webinar last month.

      My data is good - checked all the parameters against the Zoom knowledge article.

      First upload of 200 names only 199 accepted - it appears that Zoom doesn't like row 1 but the template doesn't call for a header row.

      My second upload of 25 names (to the same webinar) only 17 were accepted. I could find no reason why. One email may have been rejected due to a possible duplication, but all others were clean and unique.

      If you have any thoughts to share I'd appreciate it.
