Google Sheets - DATEDIF function

DATEDIF calculates the length of time between two dates. For example, given birth date of a people, we can calculate the ages as of today.

Syntax

DATEDIF(start_date, end_date, unit)

Example


Notes

  • Use "MD" as unit to calculate the number of days after subtracting the whole months.
  • Use "YM" as unit to calculate the number of months after subtracting the whole years.
  • Use "YD" to calculate the number of days between two dates as if they are in the same year. For example, DATEDIF("2/3/2008", "2/19/2020", "YD") will return 16.

Excel - IF function

Image
If function is a logic function. It does two things: Whether the criteria is met Return a value based on whether the criteria is met or not. If the criteria is met, it returns one value; if the criteria is not met, it returns a different value. The reason IF function is confusing for some Excel users is that it does two things: a logical test, AND a return value depending on the logical test result, while the name of "IF" implies it only does a logical test. If this function only returns TRUE or False, it would be much easier to understand. In the following example, there are 5 employees, each having his own budget. Column C records the exact amount of money they spent. If the actual spending is greater than budget, we call it "Over budget", otherwise, we call it "Within budget". The IF function is: =IF(C2>B2,"Over budget","Within budget") The first part, "C2>B2", is a logical test. If this is TRUE, then the IF function ...

VLOOKUP function asks for 4 things: The value you want to look up, such as name of a person The data range you want to search If the value is found in the data range, which column contains the value you want the function to return?

Excel - Hierarchical chart (Treemap)

Image
If you have hierarchical data, you can create beautiful hierarchical charts. For example, in a university, there are students of different majors in departments, and departments in schools. Suppose we have data below, showing number of students in each school, department and major. In this example, we show you how to make treemap chart. The other type of hierarchical chart is sunburst chart. The data is equivalent if all the cells are filled. I like the following format better. 1. Select the data, then click Insert > Charts > Other Charts > Hierarchical . Select Treemap .  2. A nice-looking treemap chart is shown. The blue area shows all engineering students. The orange area shows all business students. Size of each rectangle is proportional to the number of students in each major.
