Please follow the below proposed solution for the same. In the if condition I've mentioned the specific cell to validate.

Code:
Excel.LaunchExcel.LaunchAndOpenUnderExistingProcess Path: $'''C:\\Users\\Documents\\Holidays.xlsx''' Visible: True ReadOnly: False Instance=> ExcelInstance
Excel.ReadFromExcel.ReadAllCells Instance: ExcelInstance ReadAsText: False FirstLineIsHeader: True RangeValue=> ExcelData
IF IsEmpty(ExcelData[5][0]) THEN
Display.ShowMessageDialog.ShowMessage Title: $'''tet''' Message: $'''Apply some action''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed
ELSE
Display.ShowMessageDialog.ShowMessage Title: $'''tet''' Message: $'''Continue other actions''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed
END
