I'm trying to do a dashboard using an export of data from a 10km race. The Chip time is shown in minutes (elapsed) but when I click in the cell in Excel is shows a completely different format / formula (I'm not sure which).
When I bring the file into Tableau it shows as a date in the format above the chip time but I'd like to be able to show and analyse the chip time in MM:SS format. Picture attached.....

Thanks @Jan Karel Pieterse and @Peter_Bartholomew. I've attached a two line sample of the challenge. I can't ignore the date aspect because it does interfere with the MM:SS format when I try and analyse it in Tableau. The formula given I can't make work.
If you can look at the attached for 2 mins I'd be grateful.

Afraid that question is more for Tableau community. Apply General format to the time, you'll see the number. In Excel date is integer part of the number starting from 01 Jan 1900 (=1), and time is decimal part of the number. Thus dates are always will be added if your number is the equivalent of more than 24 hours.

If you use the MOD formula I suggested, it will strip off the date element.
Then copy the formula results and paste values back over the original data.
Try the read into Tableau again and this time it should show as a time and not a datetime.

I rather assumed elapsed time would work correctly with either the datetime or the time, provided the race is not run at midnight. Something that might require more careful handling is any gun/chip calibration errors that could be positive or negative. I am also puzzled by a timing system that times to the nearest minute; I am more used to 1/100ths of a second.

Peter, maybe I misunderstood something, but if you have Chip Time 33:33:00 you shall show it in Tableau as 33:33:00, not as 9:33:00.
Not related to this task, I checked for few minutes Tableau community forum - issue with converting Excel datetime representation into Tableau form exists, but I didn't dig details. Never worked with Tableau.

I've followed all of the tips and the MOD formula works to change the number into the MM:SS format but when I then cut and paste it into another column, it reverts back to the 1/1/1900 MM:SS:00 format - I'm really puzzled!
