Importing Collection?

{"ops":[{"insert":"I hope this is the correct place to ask. I have attempted to create a CSV file of my MTG singles collection for import. I've created 3 columns: Card Name, Set, Quantity. I have exported from Excel to CSV and have attempted to upload to Archidekt, but I keep getting errors indicating that my \"Quantity\" column contains \".\"\n\nI've searched my entire Excel file for \".\" but there are none in my quantity column. Does anyone have suggestions? Manually entering my list card-by-card is not an option.\n"}]}
