Today we will learn to use Excel’s LEFT and FIND formulas. But what fun it is to learn a new formula on a Tuesday?
So, we will actually learn to use these formulas to solve the problem: “extract the username from an email ID”
How is an email ID structured?
Any email ID contains 2 parts – user name and domain name.
For eg. in my email id – chandoo.d@gmail.com – chandoo.d is user name and gmail.com is domain.
So how do we get the user name out?
As you can see, username always starts at left and goes up to the symbol “@”. So, If we write a formula to fetch all the characters up to “@” symbol, it will get us the user name.
This is where LEFT() and FIND() formulas enter the scene.
What does Excel LEFT formula do?
Excel LEFT formula will let you cut a portion of text from left. For eg. =LEFT("Long",2) will give you Lo. (syntax and examples)
So, to get the email username, we need to get all the letters in the left of email ID up to the location of “@” symbol. And how do we find the position of a symbol in a text?
We use FIND formula.
FIND formula gives the location of one text in another. For eg. =FIND("do", "chandoo") will give us 5 (the location of “do” in “chandoo”).
FIND will throw an error (#VALUE!) if the text you are trying to find is not available. For eg. =FIND("peace", "world") will throw #VALUE!
Armed with these 2 formulas, now let us get that user name out of email ID
Assuming cell A1 has the email id, the formula for getting user name is =LEFT(A1,FIND("@",A1)-1)
We have to use -1 as find actually tells the position of “@” and we need all the letters up to “@”, but not “@”.
This is how it works:

Your homework:
- How would you extract the domain out of email ID? (Hint: there is a right formula for everything)
Use comments to write your answers. Don’t cheat.

CONGRATS on the book!
Thanks for this podcast. It's great to hear about your disaster and recovery. It's a reminder that we're all human. None of this skill came easily.
Thank you Oz. I believe that we learn most by analyzing our mistakes.
Hey chandoo
this really a good lesson learned
but as I have already stated in one of my previous email that it would be more helpful for us if you could release videos of your classes for us
thanks
The article gave me motivation, especially you describing the terrible disaster that you faced but how to get back from the setbacks. Thanks for that, but with video this will be more fun.
Hi Nafi,
Thanks for your comments. Please note that this is (and will be) audio podcast. For videos, I suggest subscribing to our YouTube channel. No point listening to audio and saying its not video.
You always motivate me with respect of the tools in excel. How we can really exploit it to the fullest. Thanks very much
Thank you Amankwah... 🙂
Thank you very much, Chandoo, for your excellent lessons, I am anxious to learn so valuable tips and tricks from you, keep up the great job!
I truly appreciate the transcripts of the podcasts, because as a speaker of English as a second language, it allows me to fully understand the material. It'd be great if you can add transcripts to your online courses too, I am sure people will welcome this feature.
Dashboards for Excel has arrived in Laguna Beach, CA! Thanks!
Now I need to make time to "learn and inwardly digest" its contents as one of my high school teachers would admonish us!
