Go to Plot and choose Generate Drill File. Use Excellen for the File Format with Gerber as the Drill Map File Format. Select Auxiliary Axis as Drill Origin and click Generate Drill File. This will generate two files; PTH (Plated Through-Hole) and NPTH (Non-Plated Through-Hole). The PTH file will contain the locations for via's and through-hole components.
It might be useful to use "PTH and NPTH holes in single file" if you want to process all holes in one go.

## Generating the G-code
Start FlatCam and use File - Open Excellon to select the PTH file. Now double-click the file that you've just opened in the Project tab. The tab "Selected" will now activate with "Excellen Object" in the title.
