A TXT record, as the abbreviation suggests, is a record, which holds data in human-readable form and not code. It can be created for a domain name or a subdomain for many different purposes. Search engines, for instance, have different ways of verifying you're the owner of a given domain name and one of them is in fact by creating a TXT record with unique text which they provide and which you should use as the record value. The same verification method is used by some analytics platforms that check the traffic to your websites as well. Needless to say, in this case the content of the record is going to be read by a robot, but it'll still be in human-readable form. A TXT record is also used when you enable the so-called SPF protection for your e-mails so that you can shield them from being forged. In such a case, the record contains info showing that a particular electronic message is sent from a trusted and authorized mail server. You may use a TXT record for any type of other information as well, just like your business details, for instance.
