ISO-8601 String to Date in Google Sheets cell

Question

I have a bunch of ISO-8601 formatted strings in a column of my sheet. How can I get google sheets to treat them as Dates so I can do math on them (difference in minutes bet

Answer 1

Try this

=CONCATENATE(TEXT(INDEX(SPLIT(SUBSTITUTE(A1,"Z",""),"T"),1),"yyyy-mm-dd")," ",TEXT(INDEX(SPLIT(SUBSTITUTE(A1,"Z",""),"T"),2),"hh:mm:ss"))

Where A1 can be a cell with ISO-8601 formatted string or the string itself.
