    Q8 - Excel obsession.. Can you please elaborate?

  2. Karthik says:

    Hi Chandoo, the tips are simple, innovative and amazing. Thanks for giving it away for free.. you are a star.

  3. Tom says:


    I just wanted to tell you how much I appreciate what you do. The world is lucky to have you!

  4. Chandoo says:

    Thanks Karthik & Tom for the lovely & thoughtful comments. I am glad you are enjoying the podcast.


    For me Excel is a vehicle for achieving something greater. When I was working, Excel (along with Power Point) were means to communicate my thoughts, analysis & reports with my bosses, clients & colleagues.

    Now that I am working for myself (yay, no more TPS reports to be made on Friday evenings), I use Excel mainly to create examples so that millions of users around the world can learn & become awesome in their lives.

    Hi chandoo

    i am big fan/follower of your website off late have been loosing interest honest feedback for following reason
    .>>podcast are great but i guess something like excel training is much better with you tube videos i am sure podcast would be easier to make but i feel videos were better

    >> now everything on your website is more of money money and money somewhere its loosing its charm i used to visit your site every day but now once a week

    >> not much action on your site now like before u used to come up with stuff almost everyday

    hope you being a master in excel will evaluate all i highlighted with some data in past and present

    Please take my feedback as i dont want this amazing site loose its charm as i repeat i am big fan of your work "all the Best"

      Thanks for your comments Neeraj.


      1. We have an YouTube channel where we post new videos almost every month. Podcast is another way to reach to our audience and share knowledge in a new medium. It costs nothing and there is no pressure to listen. So I am not sure how adding podcasts to everything else we do can disappoint you.

      2. We are operating a for-profit company, not a charity. We try to follow 80-20 approach where 80% of time we provide good value free content and 20% of time we ask you to pay. This is the best I can do. You are free to select any other website or resources for your Excel knowledge if you do not like this.

      3. I live a busy personal life. I have friends, family and other needs to attend too. That is why once every few months we have 1 week off when no new posts are made. Given the fact that we already have more than 500 posts, 40,000+ comments, 25,000+ forum posts, I am sure how you can find something new to learn everyday.

      Again, thanks for your feedback. Please note that this is not a free lunch. I am happy to provide lots of appetizers and drinks for free. But everything has a cost.
