I am developing an application where I have to get the data from an Excel sheet and use it in the application, but I am having trouble accessing the data. Should I use Entity Framework and move the Data to a database or do I just import the data from Excel and use it?

I am developing a database using a code-first approach with entity framework.
I have the following Entity Framework query and that query has a DateTime column called by and it is obtained from MySQL, but sometimes it is NULL, and I get an error
first i create list of models in [HttpGet] action and return to view.
I created two models using fluent api in my dbcontext(ToDo, Category) what I want to achieve is that whenever I create a new ToDo object, the default value for CategoryId is specified as an id for the ‘Default’ category that I successfully created previously, I still need that relationship to be non optional to be able to use cascade deletion, but so that if not specified in a request body, the value of categoryid always assigns to 1.
I have a problem with storing multiple image paths in the database. My problem is every time I try to store the image path, only the last path is saved in the database. I don’t know why. The code saves images in the directory currently but can’t save in the database. What can I do to resolve this?
I have this POST endpoint in my ASP.NET Core Web API (with Entity Framework):
I’m claming data from following query,
I have a problem that I cannot solve. I would like to transmit the deck created by the user to my API but the problem is that the card and the deck are two different entities in my database that’s why I need to pass the information of the deck and the list card to my API to add them to my database.
