These are the formulas outlined in the video.

Prep Column - Get Numeric Value ONLY
=VALUE(CONCAT(IFERROR(MID(A2,SEQUENCE(LEN(A2)),1)+0,"")))

Count Number Of Occurrence
=COUNTIF($B$2:$B$17,D2)

Let's break down the "Prep Column - Get Numeric Value ONLY" formula.
=VALUE(CONCAT(IFERROR(MID(A2,SEQUENCE(LEN(A2)),1)+0,"")))

1) LEN(A2) - This part calculates the length (number of characters) of the text string in cell A2.
2) SEQUENCE(LEN(A2)) - This generates an array of numbers from 1 to the length of the text string in A2. For example, if the text in A2 is "12345", it will create an array like {1, 2, 3, 4, 5}.
3) MID(A2, SEQUENCE(LEN(A2)), 1) - This part extracts individual characters from the text string in A2 based on the array generated in step 2. For example, if A2 is "12345," it will extract "1," "2," "3," "4," and "5" one at a time.
4) IFERROR(..., "") - This function is used to handle errors. If the MID function encounters an error (e.g., trying to extract a character beyond the string's length), it returns an empty string (""). Otherwise, it returns the extracted character.
5) MID(A2, SEQUENCE(LEN(A2)), 1) + 0 - This part converts the extracted character into a number. When you add 0 to a character, Excel will try to convert it to a number. So, "1" becomes 1, "2" becomes 2, and so on. Non-numeric characters become 0.
6) CONCAT(...) - This function concatenates (combines) all the numeric characters obtained in step 5 into a single text string. For example, if A2 is "12345," it will concatenate "12345" as a text string.
7) VALUE(...) - Finally, the VALUE function is used to convert the concatenated text string of numbers into an actual numeric value. So, "12345" as text becomes 12345 as a number.



The overall purpose of this formula is to extract and convert numeric characters from a text string into a numeric value. Any non-numeric characters are ignored, and the result is the numeric value represented by the characters in the original string.

Let's break down the "Count Number Of Occurrence" formula step by step.
=COUNTIF($B$2:$B$17,D2)

1) COUNTIF: This is the name of the Excel function being used. It's used to count cells within a range that meet a given condition.
2) $B$2:$B$17: This is the range of cells in column B that you want to count. The $ signs before the row and column references (e.g., $B$2) make the reference absolute. This means that when you copy the formula to other cells, the range reference will not change. In this case, it's a fixed range from cell B2 to B17.
3) D2: This is the criteria or condition that you want to apply to the range. In this case, Excel will count how many cells in the range $B$2:$B$17 contain the same value as the cell D2.

So, the formula =COUNTIF($B$2:$B$17,D2) counts the number of cells in the range B2 to B17 that have the same value as the cell D2. It will return the count of occurrences of the value in cell D2 within the specified range in column B.
