You should download Intrro’s Chrome extension, accessible here to import your LinkedIn contact book.
It only takes 2 minutes to set up, like demonstrated above.
Open LinkedIn on your browser and click on the extension to start importing.
When the extension is activated, Intrro acquires your browser cookie for your current LinkedIn session from your device to visit your “Connections” page.
It then copies all your connections’ LinkedIn profile URL and aggregates publicly available information on their work and education history.
You may also track what data do Intrro capture from your LinkedIn profile here, on this article.
