Hi all.

I have an excel sheet with Col A and Col B. What I want to do is that I want to prevent the users from typing anything in Col B until they have typed anything in Col A.

eg: If col A is NUMBER and col B is USER,
then USER value should come only if there is a corresponding value in col A in the same row.

Any help is appreciated. Thanks

Did you know Excel offers Filter by Selection?
Add the AutoFilter icon to the Quick Access Toolbar. Select a cell containing Apple, click AutoFilter, and you will get all rows with Apple
Hi and welcome.

You could use the Data Validation feature...

  • Select column B
  • Select from the menu Data\ Validation
    • Allow: Custom
    • Formula: =NOT(ISBLANK(A1))
    • Ignore Blank: unchecked
    • Click on the Error Alert tab and define your alert message.
    • OK
