Error converting percentages

Hello

 

as you see in the screeshot below, when I load these percentage data, the negative ones stay as Text and I don't know why!!! I cannot convert them to number. There is no Chnage Type step in the query and I disabled automatic detection of data types..

Your column is not converted to a number type, it's still type any. As long as you have the header row in your data instead of promoting  them to headers. Ideally you'd format the Excel data as a table, and then no work would even be necessary, except to click the Get Data From Table/Range button.

Once you Promote those headers, you can probably use:

Fixed = Table.TransformColumns(PriorStep,  {{"Premium % Change", Number.FromText}})

Try to right-click on the column, Change Type, and select Percentage.

If this doesn't solve your problem, can you share the M code or explain how the column was built? Check source data as well

Not many steps at all! It just read the excel, navigate to the sheets and then converts positive percentages correctly, but it does not the negative ones!!!

 

I tried to change the '-' and the '%' with regular characters but nothing happened!

So the correct change type step (which I don't know where is executed!!!), for the first negative value of -0.3% should have been converted to -0.003
