In addition to <tables>, you can also import HTML lists into Google Sheets that are created using the <ol> or <ul> tags. Try the next function on your Google Sheet:
=ImportHTML("http://www.labnol.org/internet/tips-for-tech-startups/19483/", "list", 2)
The 25 start-up tips are listed using an Ordered HTML List and you can import the entire list into your Google Sheet with one formula. If there are multiple lists on a page, you can change the third parameter with the index of the list that you wish to fetch inside Google Docs.
It is important to note that once a table or list has been imported into Google Docs, the table won’t update itself even if the data on the source page has changed. Also, Google imports the tables as plain text and all the formatting and links will be lost.
