How can I upload my survey if its already a word document?

Sorry, but a word document can't be imported into the form builder as form. You can only import a fillable form in PDF format in the form builder.

I'm afraid you will have to consider creating the form from scratch.

Or perhaps the form you want is already in the form templates page https://www.jotform.com/form-templates/?classic, you can search and clone ready-made forms here.

Also, you can try out this method but I am not sure whether it will work 100%:

You can try importing it by first converting the word document to an HTML file, you can follow this guide: http://www.wikihow.com/Convert-a-Word-Document-to-HTML.

After that, upload the HTML file on a web hosting site or a server so that it can act as a live website. You can then follow this guide on how to import HTML forms on a website: http://www.jotform.com/help/28-How-to-Clone-an-Embedded-Form-from-a-Webpage.

Let us know how it goes.

Thanks.
