Hi, I am trying to enter data in a cell which is alpha/numeric but when I use the letter E it changes format to Scientific from General and changes the display - e.g. 13E1 when entered displays as 1.30E+02 - Any other letter is fine - eg 13A1, 13B1 etc. If I use the format painter from a cell that displays correctly and paste it over the data, it changes the display to 130 - I have tried creating a custom format but get dialog box saying excel cannot use the format you typed - any suggestions? thank you.
