When exporting tasks specific fields, (due date, start
date, staus, date competed...) are exported into a single
field called "body". Is there any way to extract this
data and return it to it's origianl field integrety?
During the export to csv, the Import and Export Wizard will ask that
you map fields, ie. make the appropriate choices to maintain the
original field to data integrity. It's the same process if you decide
to import directly into an Excel file. So, perhaps you overlooked
that mapping step...?
