I have a website I am creating locally. Some of the information is confidential and it can't be publicly displayed.

If I go to this link and drop my excel file into the viewer, will it be publicly available to any user on Zoho? Or does the file get altered to appear on a webpage and that's all it does? 

Sorry if the question is confusing, if you need me to elaborate I can.

Essentially, I want to make sure my docs aren't publicly viewable or if there is a way to make them private.

Thanks,

Tim
