That will work as long as the apostrophe shown by the OP is Excel's text
indicator. If there's actually a leading apostrophe in the cell, it results
in a value error.

I think you can just do this...

=A1/60

and then format that as mm:ss

Try this:

=timevalue("0:"&right(a1,5))

Format as mm:ss

I have time stored as text in the format 'mm:ss (e.g. '25:15)
Note
the leading apostrophe.
Every Excel function & format I try assumes the minutes are hours and
the
seconds minutes. I can manually edit cell to 0:mm:ss to get the
functionality
I need but have 2000 rows to edit...

Any ideas would be much appreciated.
