String excerpts - regex

I would like to copy a certain string (out of a longer range of strings in one cell) and show it in a different cell with Google Sheets. This is what is in the initial cell A1:A :
"String 1","String 2","String 3"
In B1:B I'd like ONLY String 3, so without the "" and the other strings.
Is this possible with spreadsheets?
Or is there any other way of doing so?

Update
So the task is to get word inside double quotes. And the mathcing string is placed in the end of text.
You may use regular expressions to deal with that, the basic formula is:
=REGEXEXTRACT(A1,"([^""]+)""$")
This will give a word inside "" from text in cell A1 at the end of text.
For example:
some text...,"Thisthat","https://www.url.com/de/Thisthat"
gives https://www.url.com/de/Thisthat
You may also use arrayformula:
=ArrayFormula(REGEXEXTRACT(A1:A3,"([^""]+)""$"))
Please, read more about this functions here and here.
Old answer
if you want strings to be on their rows, use this formula in B1:
=ArrayFormula(if(A1:A = "String 3";A1:A;""))
If you have cells in A1:A, which contain 'string 3', and you want to match them too, use this:
=ArrayFormula(if(REGEXMATCH(A1:A , "String 3"),"String 3",""))

SUM multiple values after a substring within all cells in a column in Google Sheets

For an open source chat analyser in Google Sheets, I need to extract all numeric values after a substring (Example), then total them.
For example, if a cell contains Example1 another text 123 Example500 text, Example1 and Example500 should be extracted out, and their numeric values summed to 501.
This is complicated further by needing to obtain the total for a column of messages.
What I've tried already:
=REGEXEXTRACT(A1, "Example(\d+)"): This only extracts the first matching value, but works!
=SUM(SPLIT(A1, "Example")): This works for messages that only include my target string, but falls apart when other strings are included. The output could possibly be filtered to results that start with a number, but this is very messy and possibly a red herring.
CONCATENATEing all my cells together, then searching for numbers. This is error-prone due to additional numbers within messages.
Another idea is to substitute each Example(\d+) to $1 the captured digit and space |. or replace anything else with empty string (regex101 demo). Knowing that $1 is unset on the right side of the alternation. Then split on space and sum up digits (any other occurring digits have been removed). If Example is a placeholder, replace with e.g. [[:alpha:]]+ for one or more alphabetic characters.
=IF(ISTEXT(A1);SUM(SPLIT(REGEXREPLACE(A1;"Example(\d+)|.";"$1 ");" "));0)
I added IF(ISTEXT(A1);...) for only processing text in the source field (to avoid errors). Else if empty or no text it's set to 0. Just remove if the field always contains text and this is unneeded.
Edit from #TheMaster: As a array formula, we can use BYROW
=BYROW(A:A; LAMBDA(row; IF(ISTEXT(row); SUM(SPLIT(
REGEXREPLACE(row;"Example(\d+)|.";"$1 ");" "));)))
try:
=LAMBDA(x, REGEXEXTRACT(A1, "(\w+)\d+")&
SUMPRODUCT(IF(IFERROR(REGEXMATCH(x, "\w+\d+")),
REGEXEXTRACT(x, "\w+(\d+)"), )))(SPLIT(A1, " "))
update 1:
=LAMBDA(x, REGEXEXTRACT(A1, "(\D+)\d+")&
SUMPRODUCT(IF(IFERROR(REGEXMATCH(x, "\D+\d+")),
REGEXEXTRACT(x, "\D+(\d+)"), )))(SPLIT(A1, " "))
update 2:
=INDEX(LAMBDA(xx, REGEXEXTRACT(xx, "(\D+)\d+")&
BYROW(LAMBDA(x, IF(IFERROR(REGEXMATCH(x, "\D+\d+")),
REGEXEXTRACT(x, "\D+(\d+)"), ))(SPLIT(xx, " ")), LAMBDA(x, SUMPRODUCT(x))))
(A1:INDEX(A:A, MAX((A:A<>"")*ROW(A:A)))))
if you start from A2 just change A1: to A2:

Filter with REGEXMATCH in Google sheet to filter out containing text in cells

Right now I have these data and I'm trying to filter out the data containing in cell C3, C4, etc.
I have no problem filtering the regexmatch data for 1 cell as shown below
but I'm unable to do regexmatch for more than 2 cells like so for example, it seems like I'm unable to make the pipework between cells as I'll get parse error, I tried adding in "C3|C4" too.
and
The wanted output that I wanted is as below but I could only hardcode the containing text in which isn't what I'm looking for. I'm hoping that I could have some tips to regexmatch the text in more than 1 cell such that it could regexmatch the text in cell C3(Apple) and C4(Pear) and show the wanted output.
you need to use TEXTJOIN for dynamic list in C column:
=IF(TEXTJOIN( , 1, C3:C)<>"", FILTER(A2:A, REGEXMATCH(LOWER(A2:A),
TEXTJOIN("|", 1, LOWER(C3:C)))), "no input")
You may use
=IF(C3<>"", FILTER(A2:A,REGEXMATCH(A2:A, TEXTJOIN("|", TRUE, C3:C4) )), "no input")
Or, you may go a step further and match Apple or Pear as whole words using \b word boundaries and a grouping construct around the alternatives:
=IF(C3<>"", FILTER(A2:A,REGEXMATCH(A2:A, "\b(?:" & TEXTJOIN("|", TRUE, C3:C4) & ")\b")), "no input")
And if you need to make the search case insensitive, just append (?i) at the start:
=IF(C3<>"", FILTER(A2:A,REGEXMATCH(A2:A, "(?i)\b(?:" & TEXTJOIN("|", TRUE, C3:C4) & ")\b")), "no input")
See what the TEXTJOIN documentation says:
Combines the text from multiple strings and/or arrays, with a specifiable delimiter separating the different texts.
So, when you pass TRUE as the second argument, you do not have to worry if the range contains empty cells, and the regex won't be ruined by extraneous |||.
Test:

Get just X number of strings from a comma separated cel

having real trouble finding a succinct solution to this simple problem. Currently I have cells which contain many comma separated items. I just want the first 5.
ie. cell A1 =
text, another string, something else, here's another one, guess what another string here, and another, hello i'm another string, another string etc, etc, etccccc
and I'm trying to grab just the first 5 strings.
Beyond that, I wonder if I can incorporate a formula such as =LEN(A1)>20
Currently I do this with numerous; =IFERROR(INDEX( SPLIT(C31,","),1)) then =IFERROR(INDEX( SPLIT(C31,","),2)) etc. then run the LEN formula above.
Is there a simpler solution? Thanks so much.
Try,
=split(replace(A1, find("|", SUBSTITUTE(A1, ", ", "|", 5)), len(A1), ""), ", ", false)
For Excel, with data in A1, in B1 enter:
=TRIM(MID(SUBSTITUTE($A1,",",REPT(" ",999)),COLUMNS($A:A)*999-998,999))
and copy across:
To get all 5 substrings into a single cell, use:
=LEFT(A1,FIND(CHAR(1),SUBSTITUTE(A1,",",CHAR(1),5))-1)
=ARRAY_CONSTRAIN(SPLIT(A1,","),1,5)
=REGEXEXTRACT(A1,"((?:.*?,){5})")
=REGEXEXTRACT(A1,REPT("(.*?),",5))
SPLIT to split by delimiter
ARRAY_CONSTRAIN to constrain the array
REGEX1 to extract 5 comma separated values
. Any character
.*?, Any character repeated unlimited number of times (? as little as possible) followed by a ,
{5} Quantifier
REPT to repeat strings

How can I separate a string by underscore (_) in google spreadsheets using regex?

I need to create some columns from a cell that contains text separated by "_".
The input would be:
campaign1_attribute1_whatever_yes_123421
And the output has to be in different columns (one per field), with no "_" and excluding the final number, as it follows:
campaign1 attribute1 whatever yes
It must be done using a regex formula!
help!
Thanks in advance (and sorry for my english)
=REGEXEXTRACT("campaign1_attribute1_whatever_yes_123421","(("&REGEXREPLACE("campaign1_attribute1_whatever_yes_123421","((_)|(\d+$))",")$1(")&"))")
What this does is replace all the _ with parenthesis to create capture groups, while also excluding the digit string at the end, then surround the whole string with parenthesis.
We then use regex extract to actuall pull the pieces out, the groups automatically push them to their own cells/columns
To solve this you can use the SPLIT and REGEXREPLACE functions
Solution:
Text - A1 = "campaign1_attribute1_whatever_yes_123421"
Formula - A3 = =SPLIT(REGEXREPLACE(A1,"_+\d*$",""), "_", TRUE)
Explanation:
In cell A3 We use SPLIT(text, delimiter, [split_by_each]), the text in this case is formatted with regex =REGEXREPLACE(A1,"_+\d$","")* to remove 123421, witch will give you a column for each word delimited by ""
A1 = "campaign1_attribute1_whatever_yes_123421"
A2 = "=REGEXREPLACE(A1,"_+\d*$","")" //This gives you : *campaign1_attribute1_whatever_yes*
A3 = SPLIT(A2, "_", TRUE) //This gives you: campaign1 attribute1 whatever yes, each in a separate column.
I finally figured it out yesterday in stackoverflow (spanish): https://es.stackoverflow.com/questions/55362/c%C3%B3mo-separo-texto-por-guiones-bajos-de-una-celda-en...
It was simple enough after all...
The reason I asked to be only in regex and for google sheets was because I need to use it in Google data studio (same regex functions than spreadsheets)
To get each column just use this regex extract function:
1st column: REGEXP_EXTRACT(Campaña, '^(?:[^_]*_){0}([^_]*)_')
2nd column: REGEXP_EXTRACT(Campaña, '^(?:[^_]*_){1}([^_]*)_')
3rd column: REGEXP_EXTRACT(Campaña, '^(?:[^_]*_){2}([^_]*)_')
etc...
The only thing that has to be changed in the formula to switch columns is the numer inside {}, (column number - 1).
If you do not have the final number, just don't put the last "_".
Lastly, remember to do all the calculated fields again, because (for example) it gets an error with CPC, CTR and other Adwords metrics that are calculated automatically.
Hope it helps!

How can I normalize / asciify Unicode characters in Google Sheets?

I'm trying to write a formula for Google Sheets which will convert Unicode characters with diacritics to their plain ASCII equivalents.
I see that Google uses RE2 in its "REGEXREPLACE" function. And I see that RE2 offers Unicode character classes.
I tried to write a formula (similar to this one):
REGEXREPLACE("público","(\pL)\pM*","$1")
But Sheets produces the following error:
Function REGEXREPLACE parameter 2 value "\pL" is not a valid regular expression.
I suppose I could write a formula consisting of a long set of nested SUBSTITUTE functions (Like this one), but that seems pretty awful.
Can any offer a suggestion for a better way to normalize Unicode letters with diacritical/accent marks in a Google Sheets formula?
[[:^alpha:]] (negated ASCII character class) works fine for REGEXEXTRACT formula.
But =REGEXREPLACE("público","([[:alpha:]])[[:^alpha:]]","$1") gives "pblic" as a result. So, I guess, formula doesn't know what exact ASCII character must replace "ú".
Workaround
Let's take the word públicē; we need to replace two symbols in it. Put this word in cell A1, and this formula in cell B1:
=JOIN("",ArrayFormula(IFERROR(VLOOKUP(SPLIT(REGEXREPLACE(A1,"(.)","$1-"),"-"),D:E,2,0),SPLIT(REGEXREPLACE(A1,"(.)","$1-"),"-"))))
And then make directory of replacements in range D:E:
D E
1 ú u
2 ē e
3 ... ...
This formula is still ugly, but more useful because you can control your directory by adding more characters to the table.
Or use Java Script
Also found a good solution, which works in google sheets.
This did it for me in Google Sheets, Google Apps Scripts, GAS
function normalizetext(text) {
var weird = 'öüóőúéáàűíÖÜÓŐÚÉÁÀŰÍçÇ!#£$%^&*()_+?/*."';
var normalized = 'ouooueaauiOUOOUEAAUIcC ';
var idoff = -1,new_text = '';
var lentext = text.toString().length -1
for (i = 0; i <= lentext; i++) {
idoff = weird.search(text.charAt(i));
if (idoff == -1) {
new_text = new_text + text.charAt(i);
} else {
new_text = new_text + normalized.charAt(idoff);
}
}
return new_text;
}
This answer doesn't require a Google App Script, and it's still fast, and relatively simple. It builds on Max's answer by providing a full lookup table, and it also allows for case-sensitive transliteration (normally VLOOKUP is NOT case-sensitive).
Here is a link to the Google Spreadsheet if you want to jump right into it. If you want to use your own sheet, you'll need to copy the TRANS_TABLE sheet into your Spreadsheet.
In the code snippet below, the source cell is A2, so you'd place this formula in any column on row 2. Using REGEXREPLACE AND SPLIT, we split apart the string in A2 into an array of characters, then USING ARRAYFORMULA, we do the following to EACH character in the array: First, the character is converted to its 'decimal' CODE equivalent, then matched against a table on the TRANS_TABLE sheet by that number, then using VLOOKUP, a character X number of columns over (the index value provided) on the TRANS_TABLE sheet (in this case, the 3rd column over) is returned. When all characters in the array have been transliterated, we finally JOIN the array of characters back into a single string. I provided examples with named ranges as well.
=iferror(
join(
"",
ARRAYFORMULA(
vlookup(
code(split(REGEXREPLACE($A2,"(.)", "$1;"),";",TRUE)),
TRANS_TABLE!$A$5:$F,3
)
)
)
,)
You'll note on the TRANS_TABLE sheet I made, I created 4 different transliteration columns, which makes it easy to have a column for each of your transliteration needs. To reference the column, just use a different index number in the VLOOKUP. Each column is simply a replacement character column. In some cases, you don't want any conversion made (A -> A or 3 -> 3), so you just copy the same character from the source Glyph column. Where you DO want to convert characters, you type in whatever character you want replaced (ñ -> n etc). If you want a character removed altogether, you leave the cell blank (? -> ''). You can see examples of the transliteration output on the data sheet in which I created 4 different transliteration columns (A-D) referencing each of the Transliteration tables from the TRANS_TABLE sheet for different use case scenarios.
I hope this finally answers your question in a fashion that isn't so "ugly." Cheers.
