Google Sheets + Apps Script gives non-developers a powerful way to pull live real estate data without writing a full application. Here's how to set it up in under 30 minutes.
Apps Script Setup
Open your Google Sheet → Extensions → Apps Script → paste the following:
const API_KEY = 'YOUR_ZIPMARKETDATA_KEY';
const BASE = 'https://zipmarketdata.com';
function fetchMarketStats(zipCode) {
const url = `${BASE}/market-stats?zip_code=${zipCode}`;
const opts = {
method: 'get',
headers: { 'x-rapidapi-proxy-secret': API_KEY },
muteHttpExceptions: true
};
const resp = UrlFetchApp.fetch(url, opts);
return JSON.parse(resp.getContentText());
}
function updateSheet() {
const sheet = SpreadsheetApp.getActiveSheet();
const zips = sheet.getRange('A2:A50').getValues().flat().filter(Boolean);
zips.forEach((zip, i) => {
const d = fetchMarketStats(zip);
const row = i + 2;
sheet.getRange(row, 2).setValue(d.median_sale_price);
sheet.getRange(row, 3).setValue(d.median_days_on_market);
sheet.getRange(row, 4).setValue(d.yoy_price_change);
sheet.getRange(row, 5).setValue(d.market_temperature);
Utilities.sleep(400); // rate limit padding
});
}
Scheduling Auto-Refresh
In Apps Script: Triggers → Add Trigger → Choose function: updateSheet → Select event source: Time-driven → Day timer → 7am. The sheet will auto-refresh daily with fresh market data.
