Any ideas how to ingest mobile data from cellebrite in to nuix?

I have added both the file system export and a csv file with relevant messages but its not parsing the data , not sure if I require a script etc pretty new to Nuix?

Thanks  

Export the data as a UFDR file. Add that UFDR file to NUIX and it will parse it.
(assuming you're on a recent version of NUIX - not sure how far back this works)  

Yep UFDR, certainly for the last 18-24months NUIX has been in getting UFDR files.
