Well in general Plus Codes are kinda intended to be most useful in areas
that dont already have a viable postcode code system. So may not be a
viable postcode system (just using name postcode for brevity, some places
say zipcode)


But seems you want a reverse geocoder. The act of turning a location (be
that lat/long directly, or lat/long extracted from plus-code!), into an
'address' (be that a textual address, or simply a postcode!) - is the job
for a reverse geocoder.

... powered by huge lookup tables. ie a 'postcode reverse geocoder' -
literally needs a database of every postcode and its location. So searches
for the nearest postcode to the search location. Not something that can be
viably done in a 'spreadsheet' really.

Many countries have large numbers of postcodes, and so a function that has
worldwide coverage is a big database.


A webservice is typically the easiest way, as they have done the 'heavy'
lifting of importing the zipcodes, and building a search function.

Or can get databases: https://www.geonames.org/postal-codes/


This also demonstrates in theory one of advantages of plus-codes, ie the
location data is* encoded into the code itself. Rather than being 'lookup
table' based.

* mostly anyway! ironically some types - short plus-codes - still need a
geocoder lookup to extract the location!)
