I have taken this spreadsheet from last year and updated it for this year’s boxes.
You can find the new spreadsheet [HERE]
(Go File > Make a copy to copy it to your own Google Drive)
Only edit the green boxed area (by clicking the arrow and selecting from the drop-down box). You can also select a cell and use DEL to remove data from that cell.
The sheet will track what remaining vehicles and 3D styles you have yet to claim. I’ve not spent too long on this, so please let me know if you encounter any errors.
Should you open more than 500 boxes, just add new rows, select cells B510:I510 and drag them down.
