## How to find out if a text contains question? [Excel formulas]

Published on Jul 17, 2015 in Excel Howtos, Learn Excel

On Wednesday (15th July), I ran my first ever webinar, on a topic called, “How to be a BETTER Analyst?” (here is the replay link, in case you missed it).  It was a huge success. More than 1,100 people attend the live webinar and hundreds more watched the replay. As part of the webinar, we had interactive Q&A. Viewers posted their questions and I replied to as many of them as I can.

After the webinar, I wanted to make sure I covered all the questions. So I downloaded the chat history. There were more than 700 messages in it. And I am not in the mood to read line by line to find-out the questions. A good portion of chat messages were not questions but stuff like ‘hello everyone, I am from Idaho’, ‘Wow, Chandoo has beard!”, “Enjoying a beer in Belgium while watching webinar” etc. So I wanted a quick way to flag the messages as question or not.
