Count Cells that are Case Sensitive
If you are a frequent user of Microsoft Excel, you may have come across situations where you needed to add or count the cells that were casesensitive. If you have done this task manually, I would like to point out that it is the most inefficient way to do it, particularly when MS Excel has the versatility to do it in a matter of seconds. As a result of attentively reading this article, you will learn about the many adding or counting casesensitive cells.
Simple generic formula:
=SUMPRODUCT(ISNUMBER(FIND(value, range)))
Summary
You may use a formula depending on the ISNUMBER and FIND functions and the SUMPRODUCT function to calculate the number of cells that contain specified text (i.e., hold a substring), taking into consideration upper and lower case. D1 in the example displayed has the following formula, which has been written down:
=SUMPRODUCT(ISNUMBER(FIND(C1,$A$1:$A$6)))
Let’s See How This Formula Works
In this example, the purpose is to count the number of times each code appears as a substring in a casesensitive manner, as shown below. When calculating text values, the functions COUNTIF and COUNTIFS are excellent choices. However, since these functions are not casesensitive, they cannot be utilized to address this issue. To check for substrings, the FIND function should be used in conjunction with the ISNUMBER function, and the SUMPRODUCT function should be used to sum up, the results.
= FIND(C1,$A$1:$A$6)
The FIND function is casesensitive and accepts three parameters: find text, within the text, and start num. It is also casesensitive and takes three arguments. Here is the text we are searching for, and this is the text that we are searching inside. Start num is the number of characters to begin searching in find text. Because start num defaults to 1, we are not supplying a number in this instance. This is necessary since we always want FIND to begin with the first character. When finding the text is discovered inside within text, FIND returns the position of the found text as a number: When finding the text is located within text, FIND returns the position of the found text as a number:
Note: When the find text function fails to yield a result, FIND returns the #VALUE! Error.
=ISNUMBER(FIND(C1,$A$1:$A$6))
This implies that we may be using the ISNUMBER function to transform the output of the FIND function into a TRUE or FALSE value using the ISNUMBER function. A TRUE value will arise from any number, while a FALSE value will result from any error:
As demonstrated in the example, we have four substrings in column C and a variety of codes in columns A1:A6, representing the data for the designated range. Specifically, we want to know how many times each substring in C1:C4 occurs in A1:A6, and we want to know how many times each substring is casesensitive.
