I have an Excel sheet with headers of different depths and the numbers are not being read (ex.: d=-12.82m is being read as x_12_82M),

I am trying to convert from Excel to a different format, for different depths but the headers are not being read properly.
I even tried changing it manually in Excel but if I do, they will be read as part of the data and not as headers
