Trimming data in convertToValues

Hi,
Is there a way to trim the data while doing a convertToValues ?
This would be a big help when dealing with fixed file-formats, because files like these typically contain a lot of padded data which need to trimmed every time they are mapped.
Some help would be greatly appreciated.

Another option is use formatService(user trim transformer)and assign it in the Schema this helps trimming while doing convertToValues.

HTH.
