Thanks - I had a look and made a few small tweaks to our importer to deal with their column names. You should be good to go now!
A few things to keep in mind:
- Importing the inventory version will probably work best.
- Some of the properties in the CSV (eg. Tradelist, My Price, Signed) are not supported here at the moment, so those columns will be ignored.
- The condition names don't seem to map exactly, so your Near Mint cards will be called "Mint/Near Mint" here. This will automatically get translated though.
Please let me know how it goes.
