Hello,
I have the task of having to create a preview in jpg format of the first sheet of an excel file.
I tried using Open XML but you can extract an image only if it is checked save thumb option.
I have tried using office automation but, as reported by Microsoft itself, it is not advisable to use office automation from server code.
In fact, it works only under certain conditions (equal platform for example)
There is a safer way to create a preview in jpg format of a excel document (even better if it worked for word)
thanks
