If I have an Excel cell with 'General' format containing 2502241433 how do I get Excel to recognise it as YYMMDDHHMM in UTC. So in this example 2502241433 means that the time is 14:33 UTC on the 24th of Feb 2025.
This is a common format in aviation reporting.
With data in A1 you can use this formula in B1
=TEXT(20&A1,"0000-00-00 00\:00")+0
format result cell appropriately, e.g. dd mmm yyyy hh:mm
