Count the instances of each value in an array, ignoring any non-string values.Installationnpm install count-array-values --saveUsageThe exported function returns a sorted array:const count = require('count-array-values') count(['foo', 'bar', 'Bar', 451, 'bar', 'bar', 'baz', 'foo'...
For example, =COUNTIF(A2:A5,"apple?") will count all instances of "apple" with a last letter that could vary. Make sure your data doesn't contain erroneous characters. When counting text values, make sure the data doesn't contain leading spaces, trailing spaces, inconsistent use of straig...

letcount:Int64=1024letformatted=count.formatted(.byteCount(style: .memory))// "1 kB" You can also customize a byte count format style, and use this to format one or moreInt64instances. The following example creates a format style to only use kilobyte units, and to spell out the exact by...
Method 2 – Counting Specific Text in Excel The COUNTIF function can count the number of instances of a specific string in a range in Excel. Suppose we have a dataset (B4:B9) of sold items. We’ll find the total number of cells that contain the specific text “BKA”, and return the...
The image above shows the second scenario, there are multiple instances of each search value in column B. This requires a somewhat more complicated formula to get the smallest number of cells between the two search values. The order makes no difference, in other words, if search value 2 is...
