I read my first non-academic book when I was in class IX. Our school was supposed to have an audit from CBSE Delhi and we were setting up our library.

Finally, after struggling for 3 hours, I found a solution that is nowhere available on the internet and I thought it is worth sharing with my audience. So, here it is – how to move wiki pages from one project to another. Continue reading

How to align or format numbers centrally in Microsoft Excel table– TopBullets.com

Topbullets.comYou may have come across this problem while you were trying to align everything centrally, but numbers don’t go to center. All other formats like date, text and account can be centrally aligned but once you change them to numbers with comma style, the format goes out of toss.

The manager wanted everything in the table centrally aligned and my colleague was trying to explain, it was impossible. Both tried all tricks and finally, the manager had to agree with him. Today, I found one hack which helps to overcome this challenge. Continue reading
