Is there a limit for how many elements you can list in your CSV spreadsheet?

I keep receiving an import error after 5 items are uploaded from my csv import and I think I’m realizing why that is, although I can’t be certain. I’m trying to upload exhibition programs and my student in the csv spreadsheet sometimes listed 20+ artists in the creator column for a single exhibit if there were many collaborators/artists/curators etc and I’m wondering if there’s an actual limit to the number of creators and/or subjects you can list before Omeka can’t handle the data and an error occurs. Does anyone know?

I have the | symbol to separate the different artist names but I’m wondering if there’s a workaround to this?
