[Freesurfer] question about stats

I have run various batches of freesurfer on our MRI scans. Now I want to take many of the stats files from all of our subjects and export them to one giant excel document. I would like to have a separate sheet for each kind of statistic (i.e. Sheet1=LH aparc.2009a; Sheet2=RH aparc.2009a; Sheet3=LH DKT etc...) and then have all of the subjects for that statistic type be included in the appropriate, single sheet.  Is there a program that you are aware of that I can use to export the stat files to excel? I would greatly appreciate any insight or help you can offer as it is taking me forever to do this by simply copy and paste. Thank you in advance,Zach
