The Scenario
You are a sports bettor and your edge is ATS research. You want the 2022–2024 ATS records for all 14 SEC teams — home ATS, away ATS, overall ATS — in a single Google Sheet so you can build a cover percentage model before the season kicks off.
The CollegeFootballData.com API has betting line data. You have looked at the docs. The endpoint structure is not obvious, and the ATS records appear to require game-level line data that you then have to aggregate yourself — it is not a pre-built ATS summary endpoint.
That aggregation is the problem. Three seasons, 14 teams, roughly 12 games per team per season is about 500 game records you need to pull, calculate cover/no-cover for each, and roll up by team and home/away. That is an afternoon of scripting.
The bad version:
- You pull all SEC game lines for 2022 — home team, away team, spread, final score
- You write a formula to calculate cover for each game
- You realize the spread signs are inconsistent (positive spread for home, negative for away, or vice versa, depending on the game record)
- You spend an hour fixing the direction logic
- You miss the Thursday kickoff for the games you wanted to bet.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI handles the game-level aggregation and the cover calculation without requiring you to understand the spread sign convention.
Open the SheetXAI sidebar and type:
Fetch against-the-spread summary data for all SEC teams for the 2024 season and paste into my "ATS Records" sheet with columns for team, home ATS record, away ATS record, and overall ATS record.
Then extend:
Pull betting lines for every Alabama game in the 2023 season from College Football Data and paste them into my "Alabama Lines" sheet with columns for opponent, spread, over/under, and final score.
Two sheets, two prompts. The ATS summary is ready for the model. The game-level lines are ready for the deeper Alabama-specific analysis.
What You Get
"ATS Records" — season-level ATS summary for all SEC teams:
- Home ATS record — covers as the home team
- Away ATS record — covers as the road team
- Overall ATS record — total cover percentage
"Alabama Lines" — game-level lines for a single team:
- Opponent and spread — the exact number you would have bet
- Over/under — total line for O/U tracking
- Final score — for calculating covers after the fact
Both tables are model-ready. Home vs. away ATS splits tell you which teams perform better covering on the road than at home — often a sharper signal than the overall record.
What If the Data Is Not Quite Ready
Betting data has gaps and quirks that matter for modeling. SheetXAI handles them inline.
When some games have no line data
Certain non-conference games, especially early-season matchups against FCS opponents, may have no spread recorded.
In the "Alabama Lines" tab, flag any row where the spread column is blank or null with "No Line Available" in a new column. Do not remove those rows — keep them for the game log but exclude them from any ATS calculation.
When you want cover percentage calculated directly
The raw win/loss ATS record is useful, but you want cover percentage as a decimal for the model.
In the "ATS Records" tab, add a column for home cover percentage, away cover percentage, and overall cover percentage. Calculate each as covers ÷ (covers + non-covers), rounded to three decimal places. Exclude pushes from both numerator and denominator.
When you want to filter to conference games only
Non-conference ATS records are noisy because the spreads are often very large. You want only SEC vs. SEC results.
Filter the "ATS Records" tab to conference games only — where both teams are SEC members — and recalculate home ATS, away ATS, and overall ATS for just those matchups. Write the results into a new tab called "ATS Conference Only."
When you want a multi-season view to spot trends
One season of ATS data can be noise. Three seasons reveal tendencies.
Pull game-level betting lines for all SEC teams for the 2022, 2023, and 2024 seasons. For each game, calculate whether the home team covered (or if it pushed). Aggregate by team and season into a tab called "ATS by Season" with columns for team, year, home ATS record, away ATS record, and overall ATS record. Sort by year ascending within each team.
The pattern: game-level data is the raw material, aggregation is the analysis. Ask for both in one prompt.
