Boolean field value for list import
I have a Boolean field and am about to import a list of clients and ex-clients.
Can you please advise what value the excel/ csv needs to be so it marks the value of the boolean field true or false? Is a 1 and 0 right, or do I just add True (for current clients) and leave it blank for the ex-clients? The list only contains current and ex clients.
Thank you!
