upload 2500 products

i have around 2500 products .i have excel ready with all information . you have run a script and upload all products and images .
important thing to note .
we have 10 languages in our website there fore 10 lanauges .
product descriptions have already been translated and are in excel file .
All product descriiptions are same only atrribute values differ eg size , name colour price etc , however product description in 10 langugaes are all same so yu can simply copy it . good luck
