Assuming the data is mirrored by X: For illustration, lets say the board is 100mm wide, origin is right and a part 10mm from origin, is 90mm from left corner, which the software considers to be the PCB zero. Be checking bottom side when loading the data, the X coordinates are made negative. So, our part gets -10 for X coordinate. Put 100mm for board offset. The coordinate used for placement is then 100-10=90mm, which is right.
If the data is not as described above, you need to do a conversion in Excel.
