Chandoo.org is to blog to learn Microsoft Excel and Charting online. It is founded by Purna Duggirala in 2007.
After completing Computer Science degree from Andhra University, Purna went on to complete his MBA from IIM Indore in 2006 and joined Tata Consultancy Services (TCS). His work involved doing a lot of analysis and research using Excel. Purna started his website, chandoo.org several years back, but for a while it only contained posts about his family and life. In 2008 February, he wrote an article about an Excel trick that was picked up by a lot of popular blogs on the Internet. That became a good traffic source and chandoo.org started getting a lot of visitors. Excited, Purna started devoting more time towards blogging and started a few more websites. None of the other websites showed any signs of success. However, chandoo.org had started gaining traction and Purna became serious about his blog and started posting advanced tips and tutorials about using Excel to improve productivity. Both affiliate and Google Adsense revenues were good enough for Purna to eventually quit job. He has also started his training program – Excel School.
