Will importing a csv with same products add them or edit the previous ones?

[acua]

I have a small problem, i have a prestashop site which will have hundreds of products and if my supplier's prices change i will have to take every single one of them and change the price according to my supplier.

 

I saw that it is possible to import products via .csv files, but the problem is that i saw that i can import multiple products with the same code.

 

What i need from this .csv import is to actually update only the filled in sections, not replace the entire product or add a similar one with different stats.

 

Example:

 

I have this product: 1;2;120;4;5;6;product description;

and i want to modify only the price, which is the third field so i would import something like this

1;;110;;;;; and this will select the product id (which is 1) and update only the price area from 120 to 110.

 

I don't know if i made myself clear, but i hope there is something to solve this problem.

It will import them again.

 

You need to find a module that lets you update products via CSV file.

 

If you are trying to import prices from the "Price" tab (not the base product price), you can use http://www.presto-changeo.com/en/import-export-modules/84-product-prices-import.html

 

You can also check the Addons store.

I can't really find the module (for 1.5.3.1) that does exactly what i want and i don't think i have the php and mysql knowledge to make the module myself... how much would it cost me to ask someone to make it for me?
