Unity 5 UI button prefab filler script

General information for the business: making a video game
Kind of development: Customization of existing program
Description of requirements/functionality: I have a button prefab with 7 children; 3 images/sprites and 4 texts. I would like a script that reads a resource file and creates instances of the buttons with the correct text and images. The button will also contain a boolean and a string.

The script should look through a long list of missions and create buttons for the canvas location (Science Lab, Engineering, ...).

If should look at the boolean (show all missions) and display all or only missions that have not been completed.

The buttons with the correct images and text should be created in the mission panel with and a vertical scrollbar.

If the button is pressed game should go to the correct scene.
Specific technologies required: unity 5 c scripting
OS requirements: Windows
Extra notes: I am looking for a working skeleton script that I can add too. The resource file example in excel but the final file type is flexible and most likely will be online in a database.
advice is welcome on how to best accomplish this task.
