Google Sheets Count Specific Sequences - google-sheets

Question

I have a complex employee schedule spanning one year with 25 individuals in a Google Sheets format. Each individual may have more than one duty on a given day and these are delimited by commas currently. Here is a shortened and simplified sample as I cannot attach the original sheet to respect anonymity of coworkers:
1/1/2022
1/2/2022
1/3/2022
1/4/2022
1/5/2022
1/6/2022
1/7/2022
1/8/2022
1/9/2022
1/10/2022
1/11/2022
1/12/2022
1/13/2022

To ensure fairness, I need to quantify how often certain events occur. I was helped greatly by member Osm with a solution to Count the same event occurring multiple days in a row. I have worked through that solution and understand it now, but have hit another snag. I need to count the frequency of the following sequences:
-Back Up Call | Back Up Call | Night Call
-Back Up Call | Night Call | Back Up Call
-Night Call | Back Up Call | Back Up Call
I would like the output to look something like this:
Backup/Backup/Call
Backup/Call/Backup
Call/Backup/Backup
Person 1
0
0

Person 2
2
0

Person 3

So far I have tried variations of IF function but I am new to array formulas and the difference in syntax that is allowed is tripping me up. I have also begun working through using REGEXREPLACE and representing each of these various text strings as a different number and getting sums, but this does not allow me to determine the order the shifts occurred in.
Does anyone have a solution which might work for this? Thank you very much, in advance.

Answer 1

Get the count
Use this formula to get the count
=ArrayFormula(IF($E$3:$E$509="",,
{BYROW($F3:$509,
LAMBDA(v, COUNTIF(SPLIT(REGEXREPLACE(TEXTJOIN(",", 1, TRIM(REGEXREPLACE(
IFNA(REGEXEXTRACT(
TRANSPOSE(QUERY(TRANSPOSE(LAMBDA(x,y, IF(COLUMN(x)<=MAX(IF(y="",,COLUMN(x))),IF(y="","Empty", y),""))(v,TRIM(REGEXREPLACE(v, ", ,|(,)[^,]*$", "")))), " Where Col1 <> '' ")),
REGEXREPLACE(TRIM(A$2), " \| ", "|")),"NaError"), "[[:punct:]]", ""))),
REGEXREPLACE(A$2, " \| ", ","), "♥"), ","), "=♥"))),
BYROW($F3:$509,
LAMBDA(v, COUNTIF(SPLIT(REGEXREPLACE(TEXTJOIN(",", 1, TRIM(REGEXREPLACE(
IFNA(REGEXEXTRACT(
TRANSPOSE(QUERY(TRANSPOSE(LAMBDA(x,y, IF(COLUMN(x)<=MAX(IF(y="",,COLUMN(x))),IF(y="","Empty", y),""))(v,TRIM(REGEXREPLACE(v, ", ,|(,)[^,]*$", "")))), " Where Col1 <> '' ")),
REGEXREPLACE(TRIM($B$2), " \| ", "|")),"NaError"), "[[:punct:]]", ""))),
REGEXREPLACE(B$2, " \| ", ","), "♥"), ","), "=♥"))),
BYROW($F3:$509,
LAMBDA(v, COUNTIF(SPLIT(REGEXREPLACE(TEXTJOIN(",", 1, TRIM(REGEXREPLACE(
IFNA(REGEXEXTRACT(
TRANSPOSE(QUERY(TRANSPOSE(LAMBDA(x,y, IF(COLUMN(x)<=MAX(IF(y="",,COLUMN(x))),IF(y="","Empty", y),""))(v,TRIM(REGEXREPLACE(v, ", ,|(,)[^,]*$", "")))), " Where Col1 <> '' ")),
REGEXREPLACE(TRIM(C$2), " \| ", "|")),"NaError"), "[[:punct:]]", ""))),
REGEXREPLACE(C$2, " \| ", ","), "♥"), ","), "=♥")))}))
Display table
Assuming the first tab is named Sheet1, paste this formula in another sheet
=ArrayFormula({ "Persons", REGEXREPLACE(Sheet1!A2:C2, " \| ", CHAR(10)); Sheet1!E3:E, Sheet1!A3:C})
Named function
See here how you can create a named function to make the workflow easier. or make a copy of this sheet example.
and this demo on how to use it.
Notes
Keep an eye on the range $F3:$500 and $E$3:$E$500 If you have less or more than 500, adjust accordingly. I set it to 500 to avoid missing references.
