Deleting (overwriting) old data in a custom object

[Anonymous]

I need to manually import a new set of data in my custom object a few times. Each time I import a new list, some deletion of records must occur. I wonder if Marketo will automatically delete the old records in the custom object if they are no longer present in a new imported list, or do I need to clear all data in the custom object before importing a new list?

Thank you!

check the docs on how this works. Kinda thought it would create a new record on a new import, so you may need to delete data you do not want anymore.

Hi Olga,

There is no possibility to delete custom objects through import. The only way is to use the API.

Look into this product: Marketo Excel Add-in – Marketo LaunchPoint . I have never tested it, but it seems promising.

Thanks, Greg!

It looks like we are going to delete the custom object and create a new one before importing a new batch. However, I think Marketo should add this feature. I will propose it in Ideas.
