Exporting historical data
You can download historical end-of-day prices for certain securities. To download available data, follow these steps:
- Visit that company's summary page (e.g., http://finance.google.com/finance?q=nasdaq:goog).
- Click Historical Prices on the left side of the page.
- Under "Export," click Download to spreadsheet.
From your portfolio, you can also download the overview, transactions, and performance views in CSV format.
The option to download to spreadsheet varies by exchange and may not be available for all stocks. We're always working to expand our coverage, and you can stay informed about the latest from Google Finance by checking out the the Official Google Finance Blog
