Excel turning numbers into dates

[JaniceTIS05775]

I import a .csv file that automatically changes 

4840-1/2

to

2/01/4840

How can I stop this happening?  I re enter it every time but it must be something I can fix??

Thanks

@JaniceTIS05775 I suspect you "import" the civ by double-clicking on it. Then, Excel tries to be a bit too smart at times and automatically transforms text into dates if the particular text only slightly resembles a date.

From the Data ribbon, use Get Data, From CSV/Text or From Text (Legacy). That will allow you to set the correct data type for each column.

@Riny_van_Eekelen Thank you!  It's worked and now I can successfully and confidently work with the data I am sent.
