Expand Data is a real estate and location data enrichment add-on for Google Sheets™. Paste a column of addresses and get 104 data points per property — neighborhood, commercial, environmental, transit, and solar data — written live into a new sheet, typically under two minutes per hundred rows. Every address in your spreadsheet is hiding 104 answers; Expand Data writes them in with one click.

WHAT EACH ADDRESS BECOMES

Expand Data turns a plain address into property, neighborhood, environmental, commercial, and transit data:

GROUND TRUTH — rooftop-precision coordinates, standardized address, place ID, plus code, neighborhood, county, timezone, elevation

MAILING-LIST VALIDATION — deliverable / vacant / PO box flags, residential vs business, carrier route, county FIPS, using USPS® deliverability data from the Address Validation API. Clean and validate your mailing list before you send it.

PROPERTY SIGNALS — usable roof area, solar panel capacity, yearly solar energy estimate, existing panels detected, Street View availability

ENVIRONMENT — live air quality index and pollutants, 30-day air quality history, pollen levels by type, current weather and 5-day outlook

COMMERCIAL CONTEXT — the 20 nearest businesses, true establishment counts within 1 km (food, retail, healthcare, services, education — real counts, not samples), neighborhood classification, commercial density, business diversity

GETTING AROUND — transit access score (0-100), nearest stations by name and distance, rail access flag, rush-hour drive times in four directions

STREET LIFE — foot traffic level, predicted peak hours, street activity score

Every value is retrieved live from Google Maps Platform™ at the moment you run — no generative AI, no scraped data, no stale caches. Each row carries a timestamp and a sources column showing exactly how complete it is.

HOW IT WORKS

1. Open the panel, pick the column with your addresses
2. See the exact price before you run — total, volume discount, balance after
3. Your enriched results land in a new sheet. Done.

THE PRICE YOU SEE IS THE PRICE YOU PAY

Your first 10 rows are free — no card required. After that: $2.00 per row, sliding to $1.50 beyond 50 rows, and never more than $1.00 per row on jobs of 500+. The full price is shown before you confirm, and we never charge above the estimate you saw.

Addresses we can't resolve are refunded automatically — failed rows stay in your sheet with the reason, and the refund shows on your receipt.

WHO USES IT

Realtors and real estate teams shortlisting and comparing properties. Homebuyers and people relocating who want neighborhood, environmental, and transit data on a location before they commit. Marketers cleaning and validating mailing lists in bulk. Site selection analysts and property developers comparing locations at scale. Researchers who need environmental and accessibility data across many addresses at once. Anyone with an address column in Google Sheets™ and questions about the places behind it.

Whether you are enriching a handful of addresses or running property and location data on hundreds of rows in bulk, Expand Data writes the answers straight into your spreadsheet.

PRIVACY & TRUST

Your data is processed securely and never used for AI training. We request only four permissions, each with a job: access to the current spreadsheet (read your address column, write your results sheet), a connection to our service (the data has to come from somewhere), your email (your account and receipts), and the sidebar itself. No background triggers — the add-on runs only while you're using it.
