Update our website without messing

Hi,

Please send us your table structure via Contact Us form in which you want to import this CSV file.

Thanks

Hello,
I want to update our website without messing.

My need is very simple. A CSV file with two columns :

ex.:
---
Code,Inventaire
115334,334
116125,125
116616,616
---

Code is a item reference but not a DB_id.

Inventaire is the new value.

How can determine Code as a key?

I use HexData 1.1.0

Thanks!

(sorry for my english!)
