Lightning Object Creator is a tool that allows you to create custom objects and fields from a spreadsheet in a few clicks. Lightning Object Creator analyzes the spreadsheet data and suggests the best way to map it to Salesforce fields and relationships. You can also import the data from the spreadsheet into the new custom object and view it in a list view or a related list. In this case, you can use Lightning Object Creator to create a custom Project object from the spreadsheet that tracks installations and also import the data into the new object.
