I have a quite large excel file (>150 columns) and need to sort the mapped fields precisely for target destination. I use File Reader > Excel Parser > Mapper…
At the moment the fields run A, B,C…BX,BY…GZ. However after dragging the Input Schema fields onto the Mapping Table they are re-ordered A, AA, AB …GY,GZ… X,Y,Z. I need the target schema to be ordered exactly how they are done in the original input. How can this be done?
I tried Sort Snap and Sort Path as $ , $A , just various combinations to no success
Any suggestions on how to avoid ‘manually’ having to set the Fields in the default order. Assume that the default order is mandatory.

@Raph, I assume you want to do some transformation to the data, or otherwise, I don’t think you need the mapper at all; just push the data as-is to the target, without the mapper.
If it is the case that you need the mapper and want to maintain the key name order in the output data (and don’t necessarily care about the schema view), you may get by with just checking the 
Otherwise, if you absolutely need the schema view in the UI to represent the original order, attached below is a sample pipeline with an optional hack to help.
The Pad Key Names mapper prefixes the key names with spaces, keeping them all the same fixed length, based on the length of the rightmost column key name. Since spaces are first in the schema sort order, and all your key names should be upper case, the Transform Values mapper schema should keep the same key order in its input schema, while allowing you to manipulate the data for the target. The Trim Key Names mapper reverts the key names back to their original names, without spaces, while maintaining the key order.
