Bet Tracker for Excel: Screenshot Any Bet Slip, Skip the Manual Entry

Excel is still the gold standard for serious bettors

There's a reason experienced bettors keep coming back to Excel. The formula engine is more powerful than any dedicated bet tracking app, Power Query can reshape raw data in ways no dashboard can replicate, and a workbook you build yourself reflects exactly how you think about your betting — not how someone else's UI is designed.

Excel is also completely offline-capable, shareable with specific people without making your record public, and exportable in any format you need. If you've ever tried to export your history from a social bet tracker and received a useless CSV with half the fields missing, you know why owning your own workbook matters.

The problem: manual entry kills the habit

Most Excel betting spreadsheets die after a few weeks. The person who built it — often with real care, custom formulas, colour-coded rows — stops updating it because entering ten bets after a busy Sunday takes twenty minutes of focused attention.

Every bet that goes unlogged is a gap in the data. A gap in the data means your ROI calculation is wrong. A wrong ROI calculation means you can't make good decisions about where to focus your action. The spreadsheet that was supposed to give you an edge becomes useless the moment you fall behind on entry.

This is the problem S2S Bets is built to solve. Read our full guide on how to track sports bets for the broader picture — this page focuses on the Excel-specific workflow.

How S2S Bets works with Excel

S2S Bets connects to workbooks stored in OneDrive — either Microsoft 365 personal or business accounts. Once connected, the workflow is:

1. Place your bet on any sportsbook as you normally would.
2. Screenshot the bet slip confirmation on your phone. This is probably already something you do.
3. S2S Bets reads the screenshot using on-device machine learning — no data is sent to an external server before this step.
4. A new row appears in your workbook with Date, Sport, Book, Selection, Market, Odds, and Stake already populated.

The first time you do this takes under a minute. After that, each bet is logged in the time it takes to take a screenshot.

Excel-specific advantages

Excel users often choose it over Google Sheets for specific capabilities — and S2S Bets doesn't take any of that away.

Power Query for advanced analysis

Once you have a year of clean bet data, Power Query becomes extraordinarily useful. You can pull your bet rows into a separate query, unpivot by sportsbook, join to a closing lines table you maintain separately, and calculate CLV across thousands of bets. None of this is possible if your bet data lives in an app's database rather than your own workbook.

Full formula access

XLOOKUP, SUMIFS, AVERAGEIFS, array formulas — anything Excel supports works on the data S2S Bets writes. Build a P&L summary with a single formula, flag losing streaks with conditional formatting, calculate Kelly Criterion stake sizes based on your historical edge. The data is clean, typed correctly, and structured consistently.

Works with existing spreadsheets

If you already have a betting workbook — even a half-finished one from last season — S2S Bets can write to a new sheet within it. You keep all your existing formulas and structure; the app just adds data. Check out the best bet tracker spreadsheet options if you want a ready-made template to start from.

No account linking. No sportsbook credentials.

Some bet trackers claim to support Excel or offer spreadsheet exports, but they require you to link your sportsbook account through an API. This creates real problems: most offshore books have no API, many US state regulations restrict data sharing between operators and third parties, and handing over login credentials to a third-party app is a security risk full stop.

S2S Bets has no access to your sportsbook accounts because it doesn't need it. The screenshot contains everything — the book's name, the bet details, the odds, the stake. On-device ML reads the image. Your sportsbook credentials never leave your phone. This is a fundamental advantage over API-based trackers, especially for bettors using offshore sportsbooks that no API-connected tracker can touch.

All sportsbooks are supported

Because the input is always a screenshot, the list of supported books is simply: all of them. FanDuel, DraftKings, BetMGM, Caesars, PointsBet, Bet365, Bet99, Pinnacle, Bovada, BetOnline, MyBookie — if the book shows a bet slip you can screenshot, S2S Bets logs it to Excel.

This is particularly important for bettors who shop lines across multiple books. Your Excel tracker will have every bet from every book in one consistent format, ready for analysis. Unlike a Pikkit alternative or other social-first tracker, you're not limited to whichever books a platform has chosen to support.

Getting started takes two minutes

Download S2S Bets, sign in with your Microsoft account, and select the OneDrive workbook you want to use. The app will write to a sheet called "Bets" by default, or you can choose a specific sheet. Then take your first bet slip screenshot. That's the complete setup.
