SWGAide, in the nearby forum board, does some of that.
No, SWG has no feature to export resource stock to file or anything else.
However, give SWGAide a try and see the Resources panel and Inventory. Click F1 once there and see the import options. In short, SWGAide is using the in-game notes file system which is the easiest way to proceed. But if a resource is unknown here at SWGCraft you will get a message and you can add the using the add-old feature here at SWGCraft and then import those once again.
Recently was added a way to update your stock using the same notes files.
This add/subtract/correct feature use the exact same way as to import files, just that you use signs before the amount:
will add 1234 units to the amount SWGAide has in the inventory
will subtract 9876 units from...
will overwrite the amount SWGAide has with the specified amount which here is 1000000
But the rest of the notes file looks the same.
You can also export to notes file so you can kind of take stock and update, add missing resources.
Ahem, I realize there is no way to erase an entry via this feature, I will see what is sensible in that regard.
Anyway, you just export the filtered view
. This means that if you apply a filter for Copper so that you just see your entries for Copper, then just Copper is exported if you use that option. Great if you, as I do, have named containers for different resource classes
