Is Selenium can do it?

I have no experience with testing web page in SeleniumHD and I would start soon.
I have a website http://ift.tt/25ChbvM On it is a chart which time the tests need to enter data. This is time-consuming and tiring job.
I thought to SeleniunHD - but is it able to do?
- Enter data into multiple table cells, eg from an external file or a spreadsheet,
- To wait for a response from the server
- Save the result of the work file
Please answer the questions Thank you and best regards
