The first tool is a command-line tool that parses a KiCad .cmp file into a .JSON file with the component values and footprint IDs. The second tool opens the .JSON file in a browser window and uses the data to search octopart. To this data you can add the price and manufacturer ID obtained from octopart. When finished the data is saved as a CSV, which octopart accepts and can be used to create a shopping cart (I think).
