Open Calc and populate specific cells with data

I am running Linux Mint (all systems now) and I have a spreadsheet set up for a specific task. Right now I have a work around in that I export the data and manually paste it into specific cells to create the “report” I desire. But I want to click the button in my app and open OpenOffice.Calc from my application then export three text fields to the Calc sheet.

Can this be done? And if so, how? I am stumped using the built in Reports function of the dev tool… and I feel this is probably going to be an easier way of doing what I want.
