Normal Distribution confirmation

Dear Excel Forum Guys!

I'm trying to confirm if my extensive data (more than 1000 points) fits a normal distribution. I already know how to do it with histograms but i'm looking for a more accurate manner. Do you have any ideas??

I believe that probably the answer is related with chi-square test...but unfortunately I dont known how can I do it!

Please Help me!

Thank you so much in advance

Maybe this

Thank you so much!!! Problem completely solved!
