How do I add Zero's like 000513232. It keeps removing the zeros and it becomes 513232.. Stupid Excel trying to be to smart...

 

Are you going to perform calculations on the number? If not, just enter a apotrophe (single quote, really) in front of the number.
I.e.,
'000513232

Otherwise... try looking into cell formatting...

 

Format cells and use "Text" in the Number Tab.

 

This one I do know... go to Format/Custom... select the Number tab then select Custom in the Category box... find 0 under type (scrolling window)... then add the number of 0's you want in the entry window under Type.
