Excel/Data Validation


QUESTION: Dear Tom Ogilvy,

I have given Data validation with the following contents (Term , Active,Extended, Assit )for office purpose. This prevents other persons from entering other  words than those listed by me. But when someone copy data from other cells ( for eg: Assssit) and paste in the cell it is accepting.

Can you provide me a solution to avoid such mismatch so as to have effective Data validation

ANSWER: Manikandan,

Data validation is treated the same as a cell format parameter.  If you allow the formatting of a cell to be altered, then the data validation can be altered.  You need to mark the cells that you want the value to be editable by the user as unlocked, then protect the sheet and not allow formatting changes.

I unlocked the cell as advised by you and protected the sheet. But couldnt understand not allow formatting changes. Please help. I'm using excel 2010

Data protection  

when you protected the sheet you should have been given an list of parameters you could specify.    Usuually allowing to select locked or unlocked cells are checked and the other choices are unchecked.  Some of those other choices pertain to allowing the user for format.  As a minimum Leave those choices associated with formatting as unchecked (or uncheck them if they appear checked).
