The answer is "obviously not" since an Excel sheet "with 'dots' for pins" has none of the required data to create a Package Symbol. You could get the Excel sheet to a text format, like CSV, and then work from there. You would need to apply some assumptions to ease processing, but this could be done with some work. PCB Editor is going to need Pin Number, Padstack Name, X / Y location and Rotation in a CSV to import a CSV Pin file into a Package Symbol. You could start with A1 as the top left Pin Number, a "default" Padstack name to start with, an X / Y location of 0 / 0 and Rotation of 0, then work through B1, C1 and so on for the row with an increment to the X location to match the Pin pitch, then move on through the rows with Y incrementing in the Location for each row, A2, B2, C2 and so on for Pin Numbers. If you have some programming expertise, it wouldn't be that difficult to create the required CSV PIn file data to import into PCB Editor.
