How Paste text from a single cell of Excel to web by desktop recording

Hello,
have a macro, which gives me a final count of an algorithm. I again want to copy that number and paste onto a web application to execute on the basis of copied data. the important thing is that web application is fully secure and we are not able to select any data… there are some there is only one box in which i can put my number and another button to click run.

So i am able to copy data from my excel as string but how i can paste that data onto web…?
Please help me …!!

What do you mean it is fully secure? Have you tried this in IE? If you can do this as a human then you can automate it one way or another but you may need to click text or relative to text to achieve this.
