In order to convert UTM coordinates (easting and northing) to latitude and longitude you need the zone number and zone letter as well. Without these your easting / northing values could be in any of the 60 zones defined by UTM.
As for libraries, there are packages for Python, Javascript and probably others.
Sample for JS:

utm.toLatLon(easting, northing, zoneNum, zoneLetter)
//returns { latitude, longitude }

utm.fromLatLon(latitude, longitude)
//returns { easting, northing, zoneNum, zoneLetter }

For Java you can use geotools or just do the math directly, more details in this [post](https://stackoverflow.com/questions/176137/java-convert-lat-lon-to-utm). — Ionut Ticus, Sep 30 '18 at 09:41

You can use ST_Transform in Postgis if you have access to this

https://postgis.net/docs/ST_Transform.html

Example:

ST_AsText(ST_Transform(ST_SetSRID(the_geom, 27700), 4326)))
