Hello,

I was moving some data from one datatable to another using export and importing that archive into my new datatable.  
On fields that were null, when i imported my data again, it filled with a string “null”.

Hello @Thiago_Andrey_Zils,

This is expected behavior. Because CSVs do not have a built-in way to represent `null` values, they are treated as the string `"null"` on export.

Thank you,  
Heath
