There is an import/export feature supporting CSV and Excel format.
The easiest way to use this feature is to do as follow:
- You need to save your sets before using this feature (You can even save the set as empty if you want). From the dashboard, go to the account and sets menu, select each set and save them:


- Go to the Import/Export page fron the main menu while connected to your account. Then go to the export section:

- Select the set and format that you want to export and then click/tap on "Export the set".
- Now if you want to import a set, you can just update the same file you just exported with the new quantity for each card you want to update and then go to the import section:

- You select the set corresponding to your file, you upload the file by using the "Choose file" button and then click/tap on "Import the set"
- Your set will be updated!
