Once you're happy with your design, you can export the Bill of Materials as a CSV to plug into your own spreadsheet in two steps.
First, navigate to the BOM from within your project. Look for the graph icon () in the left-hand toolbar. From this page, you can then click the download icon (), also in the left toolbar, to download the BOM as a CSV.
If you'd like your BOM to be updated to include custom items that aren't in the default, we can work with you to configure this so that it can easily be slotted into your current workflow. Check out the Guide for requesting a Customised BOM and then contact us at email@example.com.
