Yahoo Finance AppsScript for Google Sheets

Code.gs

function yahooF(ticker) {
  const url = `https://query1.finance.yahoo.com/v8/finance/chart/${ticker}`;
  
  const res = UrlFetchApp.fetch(url, {muteHttpExceptions: true});  
  const contentText = res.getContentText();
  const data = JSON.parse(contentText);
 
  // Check if the result exists and has data
  if (data && data.chart && data.chart.result && data.chart.result.length > 0) {
    const regularMarketPrice = data.chart.result[0].meta.regularMarketPrice;
    console.log(regularMarketPrice);
    return regularMarketPrice;
  } else {
    console.log("Error: Unable to retrieve market price.");
    return null;
  }
}

Thank you. Found this and it is helpful.

Wondering if we can use the same code the price change percentage? I tried to replace regularMarketPrice with regularMarketChangePercent but it gave me a blank result.

Hey @SunRise8320 , I don't see a regularMarketChangePercent attribute, but I do see regularMarketDayHigh and regularMarketDayLow as well as chartPreviousClose / previousClose attributes.

"meta": {
"currency": "EUR",
"symbol": "VWCE.DE",
"exchangeName": "GER",
"fullExchangeName": "XETRA",
"instrumentType": "ETF",
"firstTradeDate": 1564383600,
"regularMarketTime": 1713540973,
"hasPrePostMarketData": false,
"gmtoffset": 7200,
"timezone": "CEST",
"exchangeTimezoneName": "Europe/Berlin",
"regularMarketPrice": 114.28,
"fiftyTwoWeekHigh": 114.66,
"fiftyTwoWeekLow": 113.92,
"regularMarketDayHigh": 114.66,
"regularMarketDayLow": 113.92,
"regularMarketVolume": 64451,
"chartPreviousClose": 115.26,
"previousClose": 115.26,
"scale": 3,
"priceHint": 2,
"currentTradingPeriod": {},
"tradingPeriods": [],
"dataGranularity": "1m",
"range": "1d",
"validRanges": []
},

Would returning something like this meet your needs :

if (data && data.chart && data.chart.result && data.chart.result.length > 0) {
    const regularMarketPrice = data.chart.result[0].meta.regularMarketPrice;
    const yesterdayClose = data.chart.result[0].meta.previousClose;
    return ((regularMarketPrice - yesterdayClose) / yesterdayClose) * 100;
  } else {
    console.log("Error: Unable to retrieve market price.");
    return null;
  }

@daverich204 Thank you! I don't recall where I saw that regularMarketChangePercent attribute, maybe it was a function I saw somewhere.

Hi, thanks for providing this, it is really helpful

Do we have possibility of getting all information that are typically listed on the Yahoo Finance page, for example marketcap, PE, Volume Data and so on. Also If i need to fetch a specific date price, how can I do that

Proposed updated version for dynamic attribute request.

function yahooF(ticker, attribute = "regularMarketPrice") {

  if (!ticker || typeof ticker !== 'string') {
    console.log("Error: Ticker is required and must be a string.");
    return null;
  }
  
  if (!attribute || typeof attribute !== 'string') {
    console.log("Error: Attribute is required and must be a string.");
    return null;
  }
  
  const url = `https://query1.finance.yahoo.com/v8/finance/chart/${ticker}`;
  
  try {
    const res = UrlFetchApp.fetch(url, {muteHttpExceptions: true});
    const contentText = res.getContentText();
    const data = JSON.parse(contentText);
    
    if (!data || !data.chart || !data.chart.result || data.chart.result.length === 0) {
      console.log(`Error: Unable to retrieve data for ticker ${ticker}.`);
      return null;
    }
    
    const meta = data.chart.result[0].meta;
    
    if (meta.hasOwnProperty(attribute)) {
      const value = meta[attribute];
      console.log(`${attribute} for ${ticker}: ${value}`);
      return value;
    } else {
      console.log(`Error: Attribute '${attribute}' not found for ticker ${ticker}.`);
      console.log(`Available attributes: ${Object.keys(meta).join(', ')}`);
      return null;
    }
    
  } catch (error) {
    console.log(`Error fetching data for ${ticker}: ${error.message}`);
    return null;
  }
}
