I'm using views data export module to output results as csv, xls, xml and txt files
I'm using Batched export (with Segment size 100) because there are many results.
I have some fields which I want to alter their values.
I have implemented hook_views_pre_render to replace field values with ones I'm getting from webservice.
The problem that some values are correctly changed, others not
Is there a solution for that?
