Those SB/CS numbers are given in the season player list EXCEL spreadsheet data downloadable for free from the Strat website when the cards become available.
The challenge is connecting the lines in the downloaded spreadsheet and the lines in the ratings book.
Remove any players in the ratings spreadsheet that are not in the online game spreadsheet.
Sort both spreadsheets by name. This should result in both spreadsheets now being in the same order.
You can now copy the ratings spreadsheet and paste to the right side in to the online game spreadsheet. In theory now you have one line for each player that has all then information for every player on a single line.
You can add a column that does a calculation to double check that. The name for each player will be there twice. In one column where it was in the online spreadsheet and one where it was in the ratings book. I am assuming here that both list the name in the same order (Last, First). If they are not the same it gets a bit more complicated as you will need a formula that will convert one of them. To make it simpler I cut and paste the two columns in to the first 2 columns of the spreadsheet so they are in columns A and B.
Now insert a column right after. This will be column C. Create a formula something like @iif(A1=B1,1,0)
Copy this formula all the way down your spreadsheet. Save the spreadsheet.
You can then sort that C column. All the values should be 1. If any are 0 that means the names were not in sync. Back track in to your process and determine why. Maybe names were listed differently in the two spreadsheets. Whatever was causing the syncing problem correct it and the redo the formula, recopy it down, and re-sort the spreadsheet. Keep at it until you get it right.
Sounds like some effort but I can usually combine 2 spreadsheets like this in a fraction of the time it takes most to hand type in selected data from one spreadsheet in to another. Of course if you type 300 words a second or something with perfect accuracy we might have a race.
