The LinkedIn Spreadsheets is a Chrome browser extension that extends LinkedIn with spreadsheet functionality. Basically, it's an extension that adds spreadsheets to LinkedIn.
The extension helps me keep information on my connections organized and provides me the autonomy to store information in grid cell manner. I thought to myself that if it is useful to me, it may be useful to others. I decided to push it to Github and publish it on the Chrome web store for free.
I have open sourced the source code under MIT license so anyone can view it, modify it, commercialize it. I used the Typescript Chrome app seed project as the boilerplate for the app, but I haven’t used much Typescript. If you have any feedback feel free to send me a tweet.
You can download the Chrome extension for free here.
The chrome extension source code can be found here. If you want to hack it you can start with modifying the files here: https://github.com/mbejda/Linkedin-Spreadsheet-Chromeapp/tree/master/app/scripts.
