Auto sort alphabetically using basic macro

Hello,
I have scoured this and other excel forums looking for a simple macro code I can drop into my excel document to auto sort alphabetically based on a column, but have been unsuccessful. I have attached my worksheet to provide context to my question.

All I need is a macro that auto sorts all the rows alphabetically (descending) based on column C ("General Topic Categories") on sheet 1. Ideally the auto sort would occur once all the data in a row has been entered (i.e. column L), but I would be fine if it auto sorted after data was entered in column C in sheet 1. Also note that this will be be growing document, so the number of rows will always be increasing. It should be obvious but I don't want the headers sorted, so the first cell that should be alphabetized will be C2

I know this can easily be done using the sort function, but I will not the one imputing the data and the individual in charge would like it auto sorted.

Thank you in advance for your help

Hello Chippy
Thanks for the help, but unfortunately it's not working Also, not every cell in a row will be populated. Any additional help would be greatly appreciated. In reality, and to make things easier, I just need the rows to auto sort alphabetically based on data in column C.

Thanks

Hello Chippy,
I GOT IT TO WORK! Thank you so much. I actually changed the code a tiny bit so that the sorting occurs when data is entered into column C (so it now says "If Target.Column = 3"). One final question, is there a way so the screen/selected cell moves with the recently alphabetized row? Currently, when data is entered into column 3 everything get alphabetized (which is great), but the selected cell stays at the bottom. I would like the selected cell to move with its row. My concern is that if there is a lot of rows, the row you are entering data into could get lost. Thanks
