Could someone point me in direction of jsids contract extension spreadsheet that I used to use few years back... I've lost it????

Happy to help, we have a lot of owners in our league who use the contract extension wizard (myself being one of them), it's a great tool. Best to save a local copy to your Google Drive (or even your computer, I have it in both locations)
