Hello, I want to prepare a sheet that user will enter a name of country. However, to prevent user enter nonexistence country, I use data validation - list type. However, user complain that this is not user friendly because she has to select country name from a very long list or type full country name. so, I'm thinking about sometime Excel can auto complete a text that I had been entered recently automatically. i.e. I enter Afghanistan once. The next time I type A, Excel auto complete with Afghanistan. I do not know how to add list of country to the list of auto complete that Excel might use. Any suggestion please?
