Hello, can someone please help me?:

The below extract shows part of a table that I'm working on.

A B C D E F Minimum SMNBER
0.00 -83.33 -75.00 -83.33 -97.56 -66.67 -97.56
-91.11 -20.00 -95.29 -50.00 -95.12 0.00 -95.29
0.00 -50.00 -50.00 -71.43 0.00 -75.00 -75.00
#DIV/0! #DIV/0! #DIV/0! #DIV/0! #DIV/0! #DIV/0! #DIV/0!

In the column SMNBER, i need to determine a formula that will detect the minimum value within the range A-F. I then need to convert the decided reference into the corresponding column title. E.g. value -97.56 will appear as E.

If anyone could help with this, I would really appreciate your help as I need to use the formula on quite a big data set.

Thanks for your help!
