Enrich a Location List With 5-Day Forecasts in a Excel workbook

The Scenario

You're an event planner. You have 10 outdoor venue locations in an Excel workbook — a column with venue names in A, city and state in B. Next weekend you're assigning event slots across these venues, and the client wants outdoor assignments to prioritize locations with dry, mild weather across the full 5-day window. The forecast data will change by Wednesday, so you need to be able to refresh it quickly, not spend two hours rebuilding a workbook.

The bad version:

• You open the OpenWeather 5-day forecast tool, search for each venue city, pull up the 3-hourly data, aggregate it mentally into daily summaries, and type the high/low temperatures and conditions into a row for each of 5 days — 10 venues × 5 days = 50 cells of manually transcribed weather data.
• The 3-hourly format doesn't give you a clean "daily high" out of the box, so you're scanning timestamps and eyeballing the peaks.
• By the time you finish, the client has already emailed asking for a preliminary recommendation, and the data you just entered is already six hours old.

You're supposed to be making venue decisions, not transcribing timestamps from a weather API sandbox.

The Easy Way: One Prompt in SheetXAI

SheetXAI is an AI agent that lives inside your Excel workbook. It reads your venue and location data, calls the OpenWeather 5-day forecast endpoint for each location, aggregates the 3-hourly data into daily summaries, and writes the results across the columns you specify.

For each location in column B, fetch the 5-day weather forecast from OpenWeather and write the daily high temp, low temp, and weather description for each of the 5 days across columns C through Q — add a 'Worst Day' column in R showing the date with the highest chance of rain or severe weather for each venue

What You Get

• Columns C–Q: 5-day forecast data, three columns per day (high temp, low temp, description), for each venue row
• Column R: the date of the worst-weather day for that venue, based on precipitation likelihood or severe condition descriptions
• Venues with ambiguous city names are flagged so you can correct the location before the client presentation

What If the Data Is Not Quite Ready

Some venue locations are listed by neighborhood name, not city name, and OpenWeather won't resolve them

For each venue in column B, check if the location resolves in OpenWeather — if not, use the city name from column A as a fallback, then fetch the 5-day forecast and write daily high, low, and description for each day into columns C through Q

You want forecast summaries condensed into one column per venue instead of spread across 15 columns

For each location in column B, fetch the 5-day weather forecast from OpenWeather and write a single condensed summary per venue into column C — format it as: 'Day 1: 18°C partly cloudy | Day 2: 14°C rain | ...' for all 5 days

You need to compare two venues side-by-side in the same row and want the worse forecast flagged

For each event row in this workbook (venue 1 in column B, venue 2 in column E), fetch 5-day forecasts for both from OpenWeather, write daily high/low for venue 1 into columns C–D and for venue 2 into columns F–G for each of 5 days, then write 'PREFER VENUE 1' or 'PREFER VENUE 2' in column H based on which has fewer severe weather days

Get the full forecast data, identify the problematic dates, and write a recommendation in one pass

Fetch 5-day forecasts from OpenWeather for all venue locations in column B, write the daily high, low, and description for each day across columns C–Q, then add a column S with a venue recommendation note: 'HIGH RISK' if two or more days have rain or storms, 'ACCEPTABLE' if one day has poor weather, 'CLEAR' if all 5 days look good

Ask for the data pull, the classification logic, and the recommendation output all at once — SheetXAI handles the aggregation and the conditional labeling inline.
