In the Media Posts worksheet, in column G of the Facebook table, apply the

XLOOKUP function to categorize the size of each post, using the value of

the Characters field for the lookup value, the Character$\_$Lookup range as

the lookup array, and the Post$\_$Lookup range as the return array. Do not

specify the if$\_$not$\_$found argument, and use $1$ for the match$\_$mode

argument.
