Excel forcing input to formula?

Hi there. Not good at Excel, and tried to Google some solution for this. Probably some gurus here will see the errror at once.
I use Excel at work for copying partorders into excel and the sending it for shipping. Some very few partnumbers tends to automaticly change when i copy it to Excel.
Also, if i type it in manually, it will change.. The numbers i type in and the output is as follow:

364570E070 - Turns to = 3,65E+75
364780E050 - Turns to = 3,65E+55

How can i make excel just accept the input as i type it in?

Thanks

Another option, File, Options, data, Uncheck the box marked "convert digits surrounding the letter E..."

Hi!
Thanks everyone for all the answers

I found that, while all answers work in their own way, the solution from Fluff13 was the one i ended up using. This because i could just do it once and not have to worry about it anymore..

Thanks again!

Glad to help & thanks for the feedback

That makes two of us, I just had a look to see if there was anything.
