In the campaign, open the character and click on the gear in the top right corner. (NOTE: If your character(s) are in a campaign, the steps are slightly different than below. Take note of any messages from the conversion process, as you may need to make manual changes.
If you have problems with the conversion, please be sure to open a bug report on that project. This importer relies on my other tool, Herolab to Foundry VTT PF2 to do the actual conversion process.
Please be aware that this module attempts to match Herolab Online items to Foundry items, and will not perform perfectly in all cases due to database differences. A module for Foundry VTT that converts and imports Herolab Online 2e characters.
