I would like to convert this to the following

Answer 1

If you only have hours and minutes, a few substitutions should do the trick:

=(IF(ISERROR(FIND("hour",A1)),"00:","")&SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,"s","")," hour", ":00"),":00 ",":")," min",""))*24

Remove the extra s first, then substitute the hour by :00 , then substitute :00 with nothing to 'stick' the hours and minutes together, finally remove the min .

If there is no hour in the text, prepend 00: and multiply the whole thing by 24 to convert the time into hours.
