Hi @Bob2245 ,
Thanks! Does the CO have associations with other objects? Or do they just standalone in HubSpot without associations? Or where do you use the CO for?
Maybe another option: first create a row in the Google spreadsheet with a HubSpot CO workflow (see below) with the CO ID (or just the unique data you need)? And then let the client paste the data in the right columns according to the object id’s you imported via the workflow to Google Sheets. More info about add data to google sheets via workflow here. Then you at least have the right spreadsheet to update the CO via a manual import.
Beside you can use the API to automate the OC import proces via “create / update schema” in this link.
