Hi @bishopjernigan 

There isn’t a native feature to automatically remove objects when corresponding data is deleted from linked Google Sheets or CSV files.

By leveraging the API, you can create a custom script that synchronizes your diagram with your data source, identifying and deleting unnecessary objects.

You can also explore the help article for more thoughts:

We also look forward to hearing from other community members and associates, who may have alternative suggestions that could better address your requirements.

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Hi @bishopjernigan, thank you for posting in the community and @Humas1985 for sharing the resources! 

Would you mind sharing more details about your use case (eg. are you creating an org chart)? This will help us better understand and share any potential options to achieve this. Thanks! 

Sure, I have a huge workforce with craze attrition. It is hard enough to keep the database (excel, csv) current but to have to come back to my org chart or  RACI chart or whatever and have to manually remove objects- that is such a pain. It’s hard enough to import them into the object types I want. There has to be some “if not in the list, delete linked object” option.
