I created this table but I forgot and set the data type for the price column  as nvarchar

Create table Product
(
 ID int primary key identity,
 ProductName nvarchar(50),
 Price nvarchar(50)
)

I want to alter datatype for column price from nvarchar to int  how can I do that?

Select the column that you want to modify data type-change Price column data type from Nvarchar to int- and click save table
