You might use Excel to track your budget, but your investments? That's less likely when stock prices change from moment to moment. Now, though, you don't have to think much about it. Microsoft has teamed with Nasdaq and market info provider Refinitiv to bring real-time stock data to Excel spreadsheets in Office 365. Type in a stock symbol, click Stocks and you can fill cells with real-time data like the price, last trade times and 52-week highs or lows. They can be used in formulas, too.
