How to count the number of cells in a row that have a number greater than 7 as part of the text such as "8 days" - excel

Question

I have a spreadsheet that has several columns. I'm only going to show data from 2 of them here, because they're the 2 that I'm dealing with in this problem.
The first column is IP Addresses. The second column is how long ago the last response was or the last response date:
Address
Last Response
10.1.1.109
10/17/2022
10.1.1.113
10/17/2022
10.1.1.137
10/17/2022
10.1.1.188
4 days
10.1.1.199
10/17/2022
10.1.21.5
10/17/2022
10.1.21.50
45 days
10.1.50.41
10/17/2022
10.1.50.71
10/17/2022
10.1.88.10
10/17/2022
10.1.88.249
6 days
10.16.6.190
4 days
10.64.0.76
28 days
10.64.3.48
45 days
What I need to do is to get a few counts worked out. I want to know how many from each IP subnet have
A response older than 1 week
A Response older then 1 month.
In the sample data you can see 3 IP subnets: 10.4, 10.16, and 10.64. I am expecting to get results like:
IP Subnet
> Week
> Month
10.1
9
1
10.16
0
0
10.64
2
1
I have a formula for the "> Week", but I don't like it. I am not able to figure out how to count based on the number at the beginning of the text in that column. I tried a formula like this:
=COUNTIFS(AllIPAddresses,"10.1.*",AllResponses, NUMBERVALUE(LEFT(AllResponses, FIND(" ",AllResponses)))&">7")
Obviously this doesn't work. It gives me a column full of 0's.
What I have working for the "> Week" column:
=COUNTIFS(AllIPAddresses,CONCAT(A2,"*"),AllResponses,"<>7 days",AllResponses,"<>6 days",AllResponses,"<>5 days",AllResponses,"<>4 days",AllResponses,"<>3 days",AllResponses,"<>2 days",AllResponses,"<>Today",AllResponses,"<>Yesterday")
But like I said, I don't like it as it is just looking at the column and not counting 8 of the options. I would prefer if I could have a way to get it to look at the column and count those whose number of days is > 7. Something simple would be great, but something that is shorter and/or simpler than what I have I'll take. And I cannot reuse that effectively for the "> month" result because then I'd have to list some 30 different options that I don't want to count.
It would be better to have it look for the 1 option that I do want.
I'm hoping for something like:
First COUNTIFS counts all the text that have a number > 7
Second COUNTIFS counts all the dates that are more than 7 days before today
=COUNTIFS(AllIPAddresses, CONCAT(A2,"*"),AllResponses, LEFT(AllResponse,2)&">7")+COUNTIFS(AllIPAddresses, CONCAT(A2,"*"),AllResponses,"<"&today()-7)
And then I can reuse this for the "> month" by changing the 7 to a 30.
Though I know this formula doesn't work.
Any assistance with this problem would be appreciated!
Some Notes about my formulas
For ease of use I have named ranges:
AllIPAddresses = A2:A700
AllResponses = B2:B700
(in my formula for > week) A2 is referring to the "10.1." so that the CONCAT will give the result of "10.1.*" to the COUNTIFS
EDIT
I have added an answer that explains why I chose the solution that I did and how I had to tweak the answers I received to make them work for my specific scenario.

Answer 1

This could be accomplished using:
=LET(data,A2:B15,
_d1,INDEX(data,,1),
_d2,INDEX(data,,2),
lr,TODAY()-IF(ISNUMBER(_d2),_d2,TODAY()-(LEFT(_d2,LEN(_d2)-LEN(" days")))),
lft,TEXTBEFORE(_d1,".",2),
unq,UNIQUE(lft),
sq,SEQUENCE(COUNTA(lft),,1,0),
mm,--(TRANSPOSE(unq)=lft),
wk,MMULT(--(TRANSPOSE(lft)=unq)*TRANSPOSE(lr>7),sq),
mn,MMULT(--(TRANSPOSE(lft)=unq)*TRANSPOSE(lr>30),sq),
stack,HSTACK(unq,wk,mn),
VSTACK({"IP Subnet","> Week","> Month"},stack))
lft uses TEXTBEFORE to get the first 2 sections of the IP address.
lr calculates the number of days of the last response compared to today.
unq is the unique values of lft (IP subnet).
wk uses MMULT to calculate the conditional count of unique IP subnet values where lr is greater than 7.
mn is the same as wk, but where lr is greater than 30.

Answer 2

Perhaps you could try:
• Formula used in cell D2
=LET(_ipaddress,TEXTBEFORE(Address,".",2),
_days,IFERROR(TODAY()-ISNUMBER(Last_Response)*Last_Response,
SUBSTITUTE(Last_Response," days","")+0),
_uip,UNIQUE(_ipaddress),
_week,BYROW(_uip,LAMBDA(x,SUM(--(x=_ipaddress)*(_days>7)))),
_month,BYROW(_uip,LAMBDA(x,SUM(--(x=_ipaddress)*(_days>30)))),
VSTACK({"IP Subnet","> Week","> Month"},HSTACK(_uip,_week,_month)))
Explanations of each named variables used to make the calculations:
• Address --> is a defined name range and refers to
=$A$2:$A$15
• Last_Response --> is a defined name range and refers to
=$B$2:$B$15
• _ipaddress --> extracts the IP Subnet using TEXTBEFORE()
TEXTBEFORE(Address,".",2)
• _days checks whether the range is a number or text, since in Excel dates are stored as a number, we are using ISNUMBER() to check which returns TRUE and FALSE for text values,
So that said, the first part of the IFERROR() checks and returns the number of days,
TODAY()-ISNUMBER(Last_Response)*Last_Response
While the second part which is a text value, we are only substituting the " days" with empty and converting it to a number as well.
SUBSTITUTE(Last_Response," days","")+0
=IFERROR(TODAY()-ISNUMBER(Last_Response)*Last_Response,
SUBSTITUTE(Last_Response," days","")+0)
• _uip --> This gives us the Unique IP SUBNET
UNIQUE(_ipaddress)
• _week --> this gives us the count for each unique values row wise and returns as an array of output, for those days which are greater than 7 days.
BYROW(_uip,LAMBDA(x,SUM(--(x=_ipaddress)*(_days>7))))
• _month --> while this gives us the count for each unique values row wise and returns as an array of output, for those days which are greater than 30 days.
BYROW(_uip,LAMBDA(x,SUM(--(x=_ipaddress)*(_days>30))))
• Last but not least, we are packing all the variables that are needed to show as an output with in an HSTACK()
HSTACK(_uip,_week,_month)
To make it look good with a proper header we are wrapping it within an VSTACK(), along with the headers, [1x3] array
Well, you can also perform such tasks quite easily using Power Query as well:
To accomplish this task using Power Query please follow the steps,
• Select some cell in your Data Table,
• Data Tab => Get&Transform => From Table/Range,
• When the PQ Editor opens: Home => Advanced Editor,
• Make note of all the 2 Tables Names,
• Paste the M Code below in place of what you see.
• And refer the notes
let
//IPAddresstbl Uploaded in PQ Editor,
Source = Excel.CurrentWorkbook(){[Name="IPAddresstbl"]}[Content],
//Date Type Changed
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Last Response", type text}}),
//Extracting the IP SUBNET
#"Extracted Text Before Delimiter" = Table.TransformColumns(#"Changed Type", {{"Address", each Text.BeforeDelimiter(_, ".", 1), type text}}),
//Replacing " days" in last response column
#"Replaced Value" = Table.ReplaceValue(#"Extracted Text Before Delimiter"," days","",Replacer.ReplaceText,{"Last Response"}),
//Removing " 12:00:00 AM" from Date Time since we changed the data type of lastresponse as text
#"Extracted Text Before Delimiter1" = Table.TransformColumns(#"Replaced Value", {{"Last Response", each Text.BeforeDelimiter(_, " 12:00:00 AM"), type text}}),
//Adding custom column return the numbers of days
#"Added Custom" = Table.AddColumn(#"Extracted Text Before Delimiter1", "Custom", each if Value.Is(Value.FromText([Last Response]), type number) then [Last Response] else Date.From(DateTime.LocalNow()) - Value.FromText([Last Response])),
//Changing the data type of the custom column to ensure they are numbers
#"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", Int64.Type}}),
//Removing unwanted columns
#"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"Last Response"}),
//Returning 1 for those days which are more than 7 else returning as 0
#"Added Conditional Column" = Table.AddColumn(#"Removed Columns", "> Week", each if [Custom] > 7 then 1 else 0),
//Returning 1 for those days which are more than 30 else returning as 0
#"Added Conditional Column1" = Table.AddColumn(#"Added Conditional Column", "> Month", each if [Custom] > 30 then 1 else 0),
//Grouping by each IP Address
#"Grouped Rows" = Table.Group(#"Added Conditional Column1", {"Address"}, {{"> Week", each List.Sum([#"> Week"]), type nullable number}, {"> Month", each List.Sum([#"> Month"]), type nullable number}}),
//Renamed the IP Address Column
#"Renamed Columns" = Table.RenameColumns(#"Grouped Rows",{{"Address", "IP SUBNET"}})
in
#"Renamed Columns"
• Change the Table name as SUBNETtbl before importing it back into Excel.
• When importing, you can either select Existing Sheet with the cell reference you want to place the table or you can simply click on NewSheet

Answer 3

Answer chosen information
I choose the answer by P.b because I was able to get it to work for me first. I did have to tweak the code he provided like this:
=LET(data,AllData, _d1,INDEX(data,,1)
, _d2, INDEX(data,,4)
, lr, TODAY()-IF(ISNUMBER(_d2),_d2,TODAY()-(IF(_d2="Today","0",IF(_d2="Yesterday","1",LEFT(_d2,LEN(_d2)-LEN(" days"))))))
, lft, TEXTBEFORE(_d1,".",2)
, unq, UNIQUE(lft)
, sq, SEQUENCE(COUNTA(lft),,1,0)
, mm, --(TRANSPOSE(unq)=lft)
, wk, MMULT(--(TRANSPOSE(lft)=unq)*TRANSPOSE(lr>7),sq)
, mn, MMULT(--(TRANSPOSE(lft)=unq)*TRANSPOSE(lr>30),sq)
, stack, HSTACK(unq, wk, mn)
, VSTACK({"IP Subnet", "> Week", "> Month"}, stack))
This is what I was able to get working for me. It gives me the list of IP Subnets and the counts of how many of the IPs' "Last Response" was longer than 7 days or 30 days.
I have also used the Power Query example provided by Mayukh Bhattacharya. I was able to get this working as well. I did not test out the "let" formula that he provided as I already have a "let" formula working. I didn't chose that answer as the solution only because I was able to get the other "let" formula working first. I did have to tweak this answer as well in Power Query to look like this:
let
//AllData Uploaded in PQ Editor,
Source = Excel.CurrentWorkbook(){[Name="AllData"]}[Content],
//Date Type Changed
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Last Response", type text}}),
//Extracting the IP SUBNET
#"Extracted Text Before Delimiter" = Table.TransformColumns(#"Changed Type", {{"Address", each Text.BeforeDelimiter(_, ".", 1), type text}}),
//Replacing " days" in last response column
#"Replaced Value 1" = Table.ReplaceValue(#"Extracted Text Before Delimiter"," days","",Replacer.ReplaceText,{"Last Response"}),
//Replacing the "Today" and "Yesterday" with numbers
#"Replaced Value 2" = Table.ReplaceValue(#"Replaced Value 1", "Yesterday", "1", Replacer.ReplaceText, {"Last Response"}),
#"Replaced Value 3" = Table.ReplaceValue(#"Replaced Value 2", "Today", "0", Replacer.ReplaceText, {"Last Response"}),
//Removing " 12:00:00 AM" from Date Time since we changed the data type of lastresponse as text
#"Extracted Text Before Delimiter1" = Table.TransformColumns(#"Replaced Value 3", {{"Last Response", each Text.BeforeDelimiter(_, " 12:00:00 AM"), type text}}),
//Adding custom column return the numbers of days
#"Added Custom" = Table.AddColumn(#"Extracted Text Before Delimiter1", "Custom", each if Value.Is(Value.FromText([Last Response]), type number) then [Last Response] else Date.From(DateTime.LocalNow()) - Value.FromText([Last Response])),
//Changing the data type of the custom column to ensure they are numbers
#"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", Int64.Type}}),
//Removing unwanted columns
#"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"Last Response"}),
//Returning 1 for those days which are more than 7 else returning as 0
#"Added Conditional Column" = Table.AddColumn(#"Removed Columns", "> Week", each if [Custom] > 7 then 1 else 0),
//Returning 1 for those days which are more than 30 else returning as 0
#"Added Conditional Column1" = Table.AddColumn(#"Added Conditional Column", "> Month", each if [Custom] > 30 then 1 else 0),
//Grouping by each IP Address
#"Grouped Rows" = Table.Group(#"Added Conditional Column1", {"Address"}, {{"> Week", each List.Sum([#"> Week"]), type nullable number}, {"> Month", each List.Sum([#"> Month"]), type nullable number}}),
//Renamed the IP Address Column
#"Renamed Columns" = Table.RenameColumns(#"Grouped Rows",{{"Address", "IP Subnet"}})
in
#"Renamed Columns"
Now that I have started using Power Query I will probably continue with it as I have more transformations on this data to work on.

Answer 4

Using new 365 functions, generate unique IPs value, and count for >7 and >30 days.
If date retrieve differences, otherwise extract days number:
=LET(IP,TEXTBEFORE(AllIPAddresses,".",2),U,UNIQUE(IP),S,SEQUENCE(COUNTA(AllIPAddresses),,1,0),D,IFERROR(TODAY()-AllResponses,TEXTBEFORE(AllResponses," ")*1),W,MMULT((TRANSPOSE(IP)=U)*(TRANSPOSE(D)>7),S),M,MMULT((TRANSPOSE(IP)=U)*(TRANSPOSE(D)>30),S),HSTACK(U,W,M))
with HSTACK combine columns results.
