Way of Inserting duplicate characters into a column list

Hi, i am really sorry with the bad title as unfortunatley i do not know how to explain it exactly. I am making a .csv file in excel for my website. I have downloaded the file from the maufacturer and it has a column named for images, but it only gives the image name so for example "bike123," "bike443," is there a way to add to every cell "bike123.jpeg", "bike443.jpeg" To be honest im not even sure this can be done in excel ? If there is another way it can be done i would be so grateful as it would save so much time. Thanks very much.

I believe this is what you are trying to do. Assuming that your image name is in colmn A, add this to column B.

A1&".jpeg"

Hi, but the image names are never the same

ok will try this, thankyou

yer it works, thankyou ever so much, both of you.
