Excel - Cell should show current date if information in that row changes

Occasional Visitor


I am not excel expert. But need to solve 1 excel issue of a user in my company and looking for some help. I attached a spreadsheet here. Column A represents all users. If any user of column A updates information in of his particular row then date in column C should show the current date. Example, if user "Neel" in row 3 updates any information from C3 to L3, then B3 should show current date. If user doesn't update anything then date should remain unchanged.

Please help me to fix this.
Thank you
