Steps on extracting data automatically from a website to your excel sheet

Only excel will allow you to extract data automatically from the web pages. There is one thing you need to pay attention that the data you want to extract from a website has to be in the format of pre-data format or tables. If the data is not in one of these formats, you have to win another battle to convert the data into one. After that, you will be able to save it in your excel sheet.

Extracting data automatically from Google finance pages

So, let’s assume you don’t have to fight that battle right now, and you have found a website where the data is in one of these formats, and now you have to extract it automatically to your excel sheet.

  • First, you need to open your excel sheet where you would like to save the automatically extracted data from one of the google finance pages. Open the data ribbon and select the web command on the top left corner of the excel sheet. 
  • A new web query box will appear on your screen, and you will have to paste the link of the Google finance page in the dialog box and click on the go.
  • The web page will appear inside the dialog box and then spot the yellow arrow in the query box
  • Now, it is time to select the data you want to extract over the yellow arrows. The data will get highlighted, and the yellow arrows will become green.
  • Once your data is selected, now it is time to import it from the web page to your excel sheet. When you click on the import button, a new dialog box will appear, and the system will ask you for the location of the data. You will have to select a cell in the excel sheet and save it. 
  • Once the data starts getting extracted from the web page to your excel workbook, you might get a cryptic message, but you need to hit OK. Don’t worry, aliens have not attacked your system. It is just a simple message that your excel sheet is populating. 
  • Once the importing process gets completed, you will see the data in your excel sheet.
