I've updated the Sports Bet Tracking spreadsheet template with some of the features you've been requesting! The upgrades include:
American or Decimal Odds
Choose between American or Decimal odds by using a drop down list on the first sheet. All bets need to use the same odds type and you shouldn't change it once set.
Decimal odds (European odds) represent the potential return of a bet, including the original stake, as a multiple of the stake. The odds are presented as a single number, usually with two decimal places. Example: 2.5
American odds, also known as moneyline odds, are a popular format for expressing the likelihood of a particular outcome in sports betting, especially in the United States. American odds can be positive or negative numbers and indicate how much profit a bettor would make on a $100 wager if the bet is successful. They provide a straightforward way for bettors to understand the potential profit or risk associated with a particular bet. Example: -205, +155
Change to Macro Enabled Worksheet
The format of the bet tracking spreadsheet has been changed from .xlsx to .xlsm as I've added a few simple macros.
Click the "Add New Bet" button to input a new bet. Previously you had to scroll to the bottom of the Bet Tracker sheet to add a new bet and potentially drag down all formulas to track the stats. Now the newest bet will always be at the top and you won't have to manually manipulate any formulas.
If you want to clear all your bets there is a button that will do that but be careful - the action cannot be undone.
I don't think macros will work on MAC/iOS/APPLE devices, so you might have to manually drag down the formulas.
