What the spreadsheet never did
A spreadsheet is a fine place to record a card and a poor place to record its value. The value column is only right on the day you typed it, nobody retypes it for 400 cards, and a wrong card number stays invisible until you try to sell. SnapCard fills every field from the scan and ties the value to recorded sales, so the inventory stays right without you maintaining it.
The trade-off is scope. The app tracks what you scan into it, and there is no CSV export today, so SnapCard is the record rather than a feed into another one.
| Field | Where it comes from |
|---|---|
| Player, set, year, card number, parallel | Identified from the scan |
| Grade and cert number | Read from a PSA, BGS, SGC or CGC slab; a raw card gets a PSA-scale estimate instead |
| Current value | Recent sold prices, or a manual price you set to override them |
| Purchase price and date | Entered by you, so the card knows what it cost |
| Sold date and price | Entered by you when the card leaves the collection |
| Binder | Suggested from the scan, or chosen by you |
