One of the most common comments we get here is “how does xxx formula works?” Even though there is vast documentation on excel formulas including the built-in help in MS Office, often it is difficult for us to learn a formula quickly and use it in a snap. So to help new users of excel learn the most frequent formulas I have built an excel formula helper page.
The page currently lists about 50 most commonly used excel formulas along with 1 index card for each to explain,
- what the formula does
- what is its syntax
- 2 examples to understand how it works
see an example:
The good thing about these index cards is, they use simple day to day English to explain the formulas, so I am guessing they are a great way for new users to learn and use the formulas.
I have tried to keep the page simple so that anyone can come and learn a few formulas quickly. Play around with it and let me know if this is useful (of if something is funny / broken)
Here is the link: excel formula helper – 50 day to day formulas explained in plain English

Great Chandoo. Keep it up, Looking forward more from BYOD..
Thanks
With Excel 2013 the pivot table could be connected to the data model which provides a distinct count.
This will do for invoice count
=COUNTIF(F:F,H12)
Instead of
=COUNTIFS(sales[SELLER],$H12)
Excellent document. How did you make the last graphic? Witch app. Thanks for answer.
Can someone tell me what =countif(sales[date],sales[date]) is counting? The value is 19. Its found in the =SUMPRODUCT(IF(sales[SELLER]=H12,1/COUNTIFS(sales[SELLER],H12,sales[date],sales[date]),0))
Hi Chris,
=countif(sales [date],sales[date]) function is counting the unique dates in the table.

Excellent document!
Can you explain more about the calculation on Weighted consistency? More specific the small number is 0,00001 ?
How come the number should be smaller if there is more sellers?
Hi,
Not understood this formula: {=SUMPRODUCT(IF(sales[SELLER]=H12,1/COUNTIFS(sales[SELLER],H12,sales[date],sales[date]),0))}
Please explain.
Thanks.
