If you mean to copy a text from a form on your computer, yes that is possible. If you mean to copy the whole form, I don't think that is possible.
For adding texts, you can use our Text field:
Wher can i take text from that will paste onto text box?
You said you have a form on your computer, you can copy/paste it from there. I may have misunderstood your question so any additional information for that is greatly appreciated.
If your form is in fillable PDF format, you can import it to Jotform then you can download it back later, send it to your clients to start collecting submissions.
