The documentation for pattern matching for Google Sheets has not been helpful. I've been reading and searching for a while now and can't find this particular issue. Maybe I'm having a hard time finding the correct terms to search for but here is the problem:
I have several numbers (part numbers) that follow this format: ##-####
Categories can be defined by the part numbers, i.e. 50-03## would be one product category, and the remaining 2 digits are specific for a model.
I've been trying to run this:
=countif(E9:E13,"50-03[123][012]*")
(E9:E13 contains the part number formatted as text. If I format it any other way, the values show up screwed up because Google Sheets thinks I'm writing a date or trying to do arithmetic.)
This returns 0 every time, unless I were to change to:
=countif(E9:E13,"50-03*")
So it seems like wildcards work, but pattern matching does not?
As you identified and Wiktor mentioned COUNTIF only supports wildcards.
There are many ways to do what you want though, to name but 2
=ArrayFormula(SUM(--REGEXMATCH(E9:E13, "50-03[123][012]*")))
=COUNTA(FILTER(E9:E13, REGEXMATCH(E9:E13, "50-03[123][012]*")))
This is a really big hammer for a problem like yours, but you can use QUERY to do something like this:
=QUERY(E9:E13, "select count(E) where E matches '50-03[123][012]' label count(E) ''")
The label bit is to prevent QUERY from adding an automatic header to the count() column.
The nice thing about this approach is that you can pull in other columns, too. Say that over in column H, you have a number of orders for each part. Then, you can take two cells and show both the count of parts and the sum of orders:
=QUERY(E9:H13, "select count(E), sum(H) where E matches '50-03[123][012]' label count(E) '', sum(H) ''")
I routinely find this question on $searchEngine and fail to notice that I linked another question with a similar problem and other relevant answers.

I'm trying to keep lines that contain the word "NOA" in a column A which has many multi-line cells as can be viewed in this Google Spreadsheet.
If "NOA" is present then, I would like to keep the line. The input and output should look like the image which I have "working" with too-many helper cells. Can this be combined into a single formula?
Theoretical Approaches:
I have been thinking about three approaches to solve this:
ARRAYFORMULA(REGEXREPLACE - couldn't get it to work
JOIN(FILTER(REGEXMATCH(TRANSPOSE - showing promise as it works in multiple steps
Using the QUERY Function - unfamiliar w/ function but wondering if this function has a fast solution
Practical attempts:
FIRST APPROACH: first I attempted using REGEXEXTRACT to extract out everything that did not have NOA in it, the Regex worked in demo but didn't work properly in sheets. I thought this might be a concise way to get the value, perhaps if my REGEX skill was better?
ARRAYFORMULA(REGEXREPLACE(A1:A7, "^(?:[^N\n]|N(?:[^O\n]|O(?:[^A\n]|$)|$)|$)+",""))
I think the Regex because overly complex, didn't work in Google or perhaps the formula could be improved, but because Google RE2 has limitations it makes it harder to do certain things.
SECOND APPROACH:
Then I came up with an alternate approach which seems to work 2 stages (with multiple helper cells) but I would like to do this with one equation.
=TRANSPOSE(split(A2,CHAR(10)))
=TEXTJOIN(CHAR(10),1,FILTER(C2:C7,REGEXMATCH(C2:C7,"NOA")))
Questions:
Can these formulas be combined and applied to the entire Column using an Index or Array?
Or perhaps, the REGEX in my first approach can be modified?
Is there a faster solution using Query?
The shared Google spreadhseet is here.
Thank you in advance for your help.
Here's one way you can do that:
=index(substitute(substitute(transpose(trim(
query(substitute(transpose(if(regexmatch(split(
filter(A2:A,A2:A<>""),char(10)),"NOA"),split(
filter(A2:A,A2:A<>""),char(10)),))," ","❄️")
,,9^9)))," ",char(10)),"❄️"," "))
First, we split the data by the newline (char 10), then we filter out the lines that don't contain NOA and finally we use a "query smush" to join everything back together.
I'm trying to write a REGEXMATCH formula for Sheets that will analyze all of the text in a cell and then write a given keyword into another cell.
I've figured out how to do this for a single keyword: for example,
=IF(REGEXMATCH(F3, "czech"),"CZ",IF(REGEXMATCH(F3, "african"),"AF",IF(REGEXMATCH(F3, "mykonos"),"MK")))
What I'm having trouble with though is writing one of these values only if two or more terms are matched in the reference cell.
If I were trying to match one of two words, I realize I could use | as in:
=IF(REGEXMATCH(F3, "czech|coin"),"CZC"
etc
But in this instance I only want to produce CZC if the previous cell contains BOTH czech AND coin.
Can someone help me with this?
try like this:
=IF((REGEXMATCH(F3, "czech"))*(REGEXMATCH(F3, "coin")), "CZC", )
multiplication stands for AND
I want to avoid duplicate code within excel formulas. Is there a method to repeat a certain code segment?
=IF(A1=1,(A1-B2-C3),(A1-B2-C3)+1)
This would be especially useful when it comes to more complex or longer sections. But: everything must be in ONE formula in ONE cell. Thanks! :-)
EDIT: This is my current code.
=IF(ISNUMBER(SEARCH(".amp",A2)),IFERROR(MID(A2,FIND("#",SUBSTITUTE(A2,"-","#",LEN(A2)-LEN(SUBSTITUTE(A2,"-",""))))+1,SEARCH(".html",A2)-FIND("#",SUBSTITUTE(A2,"-","#",LEN(A2)-LEN(SUBSTITUTE(A2,"-",""))))-5),""),IFERROR(MID(A2,FIND("#",SUBSTITUTE(A2,"-","#",LEN(A2)-LEN(SUBSTITUTE(A2,"-",""))))+1,SEARCH(".html",A2)-FIND("#",SUBSTITUTE(A2,"-","#",LEN(A2)-LEN(SUBSTITUTE(A2,"-",""))))-1),""))
It strips the long ID number out of any URL of a specific CMS. So
FIND("#",SUBSTITUTE(A2,"-","#",LEN(A2)-LEN(SUBSTITUTE(A2,"-","")))
is probably the part which occurs more than once and should be replaced for a code which does not be that duplicate-prone.
EXAMPLE: www.domain.com/path1/path2/this-is-an-article-123-dd-123456789.html --> 1234567890
EXAMPLE: www.domain.com/path1/path2/this-is-an-article-123-dd-1234567890.amp.html ->
1234567890
EXAMPLE: www.domain.com/path1/this-is-an-article-1234567890.html ->
1234567890
In google sheets, you could use REGEXEXTRACT to get what you want:
Formula in B1:
=REGEXEXTRACT(A1,"\d{8,}")
Place the complex common sub-expression in its own cell and refer to that cell.
EDIT#1:
As an alternative, you can use a Named Formula for the sub-expression:
Named Formula
So here is another way of finding the code in Excel:
Here is the formula in Cell B1 which needs to be confirmed by pressing Ctrl+Shift+Enter, then drag it down to apply across board:
{=FILTERXML("<data><a>"&SUBSTITUTE(MID(A1,LARGE(IF(MID(A1,ROW($A$1:INDEX($A:$A,LEN(A1))),1)="-",ROW($A$1:INDEX($A:$A,LEN(A1)))),1)+1,LEN(A1)),".","</a><a>")&"</a></data>","/data/a[1]")}
For the logic behind this formula you may give a read to this article: Extract Words with FILTERXML.
Cheers :)
Ps. it seems that GoogleSheet has out performed Excel in some area already.
I have a string variable containing school names and I need to find all the possible combination of each word in this string variable in stata:
For example variation of a word "Academy" would be:
Academy,
Academy,
acdamey,
aacdemy,
dmcaamy,
aacedmy,
and so on.
I need this to standardize the raw data of school names, which has many typos of each word due to data entry issues, like the ones given above for "academy".
Depending whether your data is already in the Excel sheets or a file, you can either use regex trying to match all possible combinations (and probably fix them when found) or parse the strings first before bringing them into Excel. In either case you could make a file (or Excel list/table/area/etc.) that includes all the common typos and pick each typo as regex match to use when comparing to your actual input.
Making regexp that would actually find all possible cases is next to impossible, especially if there are cases where very similar (but correct) names for schools exist. In any case direct regexps would be very messy and complex, so I would advice you to parse the data by finding first the correct form, excluding it and then using (greedy) search/regex to find the typoed versions. You can then save the typos to use them as a filter/match/pattern.
To get some sort of starting ideas, check this links:
Regex: Search for verb roots
Read text file and extract string into Excel sheet using regex
P.s You should keep the count of all strings/school names and finally get a list of all names that did not match correct form or any of your regexp filters, so you can manually insert/correct them.
I would like to search my indexed documents in order using RegexpQuery.
For example I have 2 Document
text: Oracle unveils better than expected quarterly results.
text: Research In Motion shares gained almost 13 per cent on the Toronto Stock Exchange Friday, a day after the smartphone maker posted better than expected quarterly results.
So far I tried this but I got no luck.
Query regexq = new RegexpQuery(new Term("text", "^.+better.+quarterly.+results"));
Is there another way of implementing this?
Thanks
I believe a PhraseQuery fits what you are looking for better. You can use PhraseQuery.setSlop(int) to allow terms to appear between the terms of the query. This would like like:
Query pq = new PhraseQuery();
pq.add(new Term("text", "better"));
pq.add(new Term("text", "quarterly"));
pq.add(new Term("text", "results"));
pq.setSlop(10); //Or whatever is an appropriate slop value for you.
This sort of query is also supported by the standard QueryParser, as seen here, like:
text:"better quarterly results"~10
I think a PhraseQuery is most definitely the better implementation here, but...
Regarding RegexpQuery:
I believe it is intended to compare terms against the regex, and since the phrase you are searching for (I am assuming) is tokenized, no single Term matches your whole regex. You would need to index the entire field as a single Term to make this work, using StringField, KeywordAnalyzer, or similar.
I believe it works like Matcher.matches(), rather than Matcher.find(), which is to say, it must match the entire input term, rather than a portion of it. So, if you had specified "text" as a StringField, you would need to add a .* to the end to consume the rest of the input.
On a similar note, I'm not sure if it supports the use of the character "^" as the start of input, being that it is redundant in that case. I don't see it specified in Lucene's Regexp, but I have seen reference to it's use, so I'm not sure whether it would be accepted or not.
To summarize, a RegexpQuery could work like:
Query regexq = new RegexpQuery(new Term("text", ".+better.+quarterly.+results.*"));
If you used a StringField, or KeywordAnalyzer index the entire field as a single Term.
With the leading wildcard in your regexp, though, you could expect very poor performance from it (See the warning at the top of the RegexpQuery documentation).
