For each cell in the range, SUBSTITUTE removes all the o's from the text, then LEN calculates the length of the text without o's. This number is then subtracted from the length of the text with o's.
Because we are using SUMPRODUCT, the result of all this calculation is a list of items (...Read more
The Excel COUNTIF function returns the count of cells in a range that meet a single condition. The generic syntax is COUNTIF(range, criteria), where "range" contains the cells to count, and "criteria" is a condition that must be true for a cell to be counted. COUNTIF can be used to count...Read more
The Excel SUBSTITUTE function replaces text in a given string by matching. You can use SUBSTITUTE to replace or completely remove matched text. SUBSTITUTE is case-sensitive and does not support wildcards....Read more
In this example, the goal is to sum the quantities in column C by the codes in column E in a case-sensitive manner. The SUMIF function and the SUMIFS function are both good options for counting text values, and...Read more
In this example, the goal is to test a value in a cell to see if it contains a specific substring. Excel contains two functions designed to check the occurrence of one text string inside another: the SEARCH function and the FIND function. The difference is that the SEARCH function...Read more
The Excel EXACT function compares two text strings, taking into account upper and lower case characters, and returns TRUE if they are the same, and FALSE if not. EXACT is case-sensitive.Read more
Excel contains over 500 functions, with more functions added every year. That is a huge number, so where should you start? This guide provides a walkthrough of over 100 important functions in Excel with many examples and links. Click function names for details and more examples....Read more
The core of this formula is the COUNTA function, configured with an expanding range like this:
COUNTA($B$5:B5)
As the formula is copied down the column, the range starting with B5 expands to...Read more
The Excel LEN function returns the length of a given text string as the number of characters. LEN will also count characters in numbers, but number formatting is not included.Read more
In Excel's date system, dates are serial numbers beginning on January 1, 1900. January 1, 1900 is 1, January 2, 1900 is 2, and so on. More recent dates are much larger numbers. For example, January 1, 1999 is 36161, and January 1, 2010 is 40179....Read more
Does cell A1 contain "apple"? This is a surprisingly tricky problem in Excel. In this article, we look at several options, based on the functions FIND, SEARCH, ISNUMBER, and COUNTIF.Read more
The Excel FIND function returns the position (as a number) of one text string inside another. When the text is not found, FIND returns a #VALUE error.Read more
In this example, the goal is to count numbers that contain leading zeros. In cell E5, we have the code "009875" and we want to count how many times this code appears in the range B5:B16. The challenge is that Excel can be finicky with leading zeros. Technically, the values in B5:B16 are...Read more
In this example, the goal is to return a count for each color that appears in column C, using the color values already in column E as criteria. When working with data, a common need is to perform summary calculations that show total counts in different ways. For example, total counts by...Read more
First, the LEN function counts total characters in the cell B5.
Next SUBSTITUTE removes all "line returns" from the text in B5 by looking for CHAR(10) which is the character code for the return character in Windows. LEN returns the result inside of a second LEN, which counts characters...Read more
The Excel IF function performs a logical test and returns one result when the logical test returns TRUE and another when the logical test returns FALSE. For example, to "pass" scores above 70: =IF(A1>70,"Pass","Fail"). More than one condition can be tested by nesting IF functions. The IF...Read more
Traditionally, counting unique items with an Excel formula has been a tricky problem, because there hasn't been a dedicated unique function. However, that changed when dynamic arrays were added to Excel 365, along with several new functions...Read more
In this example, the goal is to create automatic row numbers starting in cell B5 that match the data entered in column C. When new data is added to the list, the row numbers should increase as required. If items are deleted, the row numbers should respond accordingly. This has traditionally been...Read more
The Excel PIVOTBY function is designed to summarize data by grouping rows and columns. The result is a dynamic summary table created with a single formula.Read more
The Excel FREQUENCY function returns a frequency distribution, which is a list that shows the frequency of values at given intervals. FREQUENCY returns multiple values and must be entered as an array formula with control-shift-enter, except in...Read more
In this example the goal is to count numbers longer than 15 digits with a formula. The COUNTIF function may seem like this logical choice. However, if you try to count very long numbers (16+ digits) in a range with the COUNTIF function, you may see...Read more
The Excel UNIQUE function extracts unique values from a range or array. The result is a dynamic array that automatically updates when source data changes. UNIQUE is not case-sensitive and works with text, numbers, dates, and other data types.Read more
The Excel OR function is a logical function used to test multiple conditions at the same time. OR returns TRUE if any condition is TRUE. If all conditions are FALSE, the OR function returns FALSE. The OR function is often used with the IF function and can be combined...Read more
