Hi Please find attached the solution.
--> I have applied data validation on the range D3:D9. --> Here the keyword used is "soni" --> If the cell contains the keyword "soni" it will shows an error. --> You can customise the error message according to your requirement. --> if the cell does not contains the keyword "soni" it will not show any error --> The formulae used in data validation is =IF(ISERROR(SEARCH("Soni",D3,1)),TRUE,NA()) Please let me know if anything else is required.
