Hello I've been asked by a data manager if I can source some advanced excel training for some of her new starters in Data. I just wonder if anyone knows of any good online packages around to help support data officers? Normally in the past, i've asked a teacher to do this but their time is taken up with other priorities these days and wanted some external 1 to 1 or online training. Any feedback would be grateful. Many Thanks
