How do you count hyperlinked numbers within a simple Google Sheet formula? Currently the =SUM(F6:CS6) (for example) does not count cells with hyperlinks.
This requires a custom function, because built-in functions cannot detect what formulas are entered in other cells, they can only access values. The discussion at Google Product Forum confirms this. There is already a custom function posted there, but I wrote another one, a bit shorter and not case-sensitive:
function countLinks(rangeNotation, range) {
var formulas = SpreadsheetApp.getActiveSheet().getRange(rangeNotation).getFormulas();
return formulas.reduce(function(acc, row) {
return acc + row.reduce(function(acc, formula) {
return acc + (/^=HYPERLINK/i.test(formula) ? 1 : 0);
}, 0);
}, 0);
}
Usage example: =countlinks("A2:E10", A2:E10). Range notation has to be passed in as a string, because the function needs the range, not the values. But this also means it needs the second parameter to be recalculated in case something changes in the referenced range.
Warning: this only counts the hyperlinks created with hyperlink formula. It will not detect the links created by pasting rich text into a cell. Those links (which really should never be created) are not detectable with Google Apps Script at present.
If you dont want to use scripts and just want a formula, this might serve you: Countifs in Google Sheets with various 'different than' criteria in same row adds +1 value
Particularly, the answer about the function COUNTA might be what you are looking for.
Try to set the format of the column you want to sum to numbers.

I have little to no coding knowledge, so apologies if the solution is too obvious!
I am trying to add a Last Modified column to a Google Sheets file. To do this, I am using an AppScript function with the following code:
function setTimestamp(x) {
if(x != ""){
return new Date();
}
}
This works fine when I use setTimestamp(x) in my file. However, I am combining this with a Zapier action that creates a new row whenever new media is added. Every time a new row is created, any existing formulas are removed.
I assume I need to use ARRAYFORMULA to apply the setTimestamp formula to newly-created rows, but it must only apply to rows that aren't blank.
I have tried the following:
={"Last Modified";ARRAYFORMULA(setTimestamp(A2:A))} -> Only worked on first row
={"Last Modified";ARRAYFORMULA(B2:B=setTimestamp(A2:A))} -> Broke the file
={"Last Modified";ARRAYFORMULA(IF(A2:A)=1,setTimestamp(A2:A),"")} -> Expected 1 argument, got 3
Is there a way I can combine the IF into the script or a better way to solve the problem?

All data is dummy data and stock photos.
Unfortunately, arrayformula does not function as an array map function for custom functions. (Even for native functions where you may expect it to work that way, it does not always, sadly.)
To handle array range, we need the custom function to handle array range directly. That also limits the number of individual calls to custom functions, which materially saves execution time.
To handle array range, there are 2 ways. I'll comment on both.
Array range directly as input of custom function
If the input is a single cell, it is read directly
If the input range spans more than a single cell, the data is read as nested lists: a list of lists of rows.
For example, A1 will be read as the data in A1. A1:B2 will be read as [[A1, B1], [A2, B2]].
You can remember it as columns of rows.
As for the input data format, numbers are taken without the display format. Texts are taken as strings.
If output is an array range, the result will automatically expend.
Thus, in your example, in B2 you can almost do
=setTimestamp(A2:A)
where setTimestamp() has been modified to
function out = setTimestamp(arr) {
out=Array(mat.length);
for (i=0;i<mat.length;i++){
j=0
if(arr[i][j] != ""){
out[i]=new Date();
}
}
return out
}
For more details, see the official help page. (Over the years, more details have become available.)
Almost, but not quite. For your direct question, above provides the answer. However, you seem to have an implicit requirement that your custom function is executed every time a new URL is found. Be careful that what happens here is that every time Google Sheet updates cell content, a new Date() is created and outputted.
Array range read within custom function
Since you know your URLs are in A2:A, and you want the output of your custom function to be B2:B, you can read and modify those ranges directly within your custom function via the Range Class.
In this route, you may find getLastRow(), getLastColumn() in Sheet and getNextDataCell() in Range convenient.
When you need to execute your custom function, you can run it manually or add onEdit() trigger to your custom function. (But onEdit() itself can mean substantial UI lag when using the sheet. It's usually more appropriate for sheets that parse external data automatically. See other triggers in the link for motions.)
In your example, you can almost do
function setTimestamp() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
var lastRow = sheet.getLastRow();
var row=1;
var cell = sheet.getRange(row,1).getValue();
while (row<=lastRow) {
if(cell.getValue() != ""){
sheet.getRange(row,2).setValue(new Date());
}
cell = sheet.getRange(row,1,lastRow).getNextDataCell(SpreadsheetApp.Direction.DOWN);
row=cell.getRow();
}
}
which will scan for all URLs in A2:A and write current time to B2:B when executed.
Again, your example implicitly points to updating only when a new URL is found. So be careful about that. Use triggers as needed.
As for the need to place formula in B1, you can (and should) reference the output of your other application in a different sheet so that you or a different application of yours can edit without conflict.
Thus, for what was asked, we have everything.
I have a cell that contains a number range, say 50-60 that I would like to apply custom number formatting to. Ideally, I'd like to be able to format that to output 50Hz-60Hz.
The syntax that works for a regular integer is #"Hz", but I can't find an in-built way to do this for dashed ranges, and I suspect it isn't possible.
Answer:
As you suspected, this isn't possible to do.
More Information:
As Tanaike has said in his above comment, the cell input 50-60 is a string - purely read as text as it contains the - character. Resultantly, Sheets does not have the functionality to use Number formatting to change the way this is displayed.
(Kind of) Workarounds:
Disclaimer: These suggestions are not perfect workarounds and depending on how the data in the cells is processed elsewhere in the sheet, these may not work. They do however provide solutions if you are looking to affect the UI only.
Workaround 1: Using a custom Number Format
You can use the format ##"Hz-"##"Hz" which will display 50Hz-60Hz for the example you give, if the input of the cell is 5060 rather than 50-60. You will however need to change the format to contain three # characters if the frequency range of the cell goes above 100:
##"Hz-"##"Hz" will make the number 5060 display as 50Hz-60Hz
###"Hz-"###"Hz" will make the number 120130 display as 120Hz-130Hz
####"Hz-"####"Hz" will make the number 14201430 display as 1420Hz-1430Hz
Workaround 2: Using an onEdit(e) Trigger
If inputting the - yourself is important, then you can use an onEdit() Apps Script trigger to change the format of the cell to include the Hz unit after-the-fact.
For this workaround, I will assume that the column your frequency ranges are in is column C.
From the Tools > Script editor menu item, you can create a function with the following code:
function onEdit(e) {
if (e.range.getColumn() != 3) {
return;
}
else {
var f = e.value.split("-");
e.range.setValue(f = f[0] + "Hz-" + f[1] + "Hz");
}
}
Make sure to change the value on the line if (e.range.getColumn() != 3) to be whichever column your frequency ranges are: this example uses the value 3 because the column is assumed to be column C, but column D would be 4, E would be 5, etc.
Save the script with the save icon, press the run button (►), and confirm the authentication of running the script.
This will automatically run whenever a value like 50-60 is inputted into column C, and will change to display 50Hz-60Hz instead.
Workaround 3: Using a Custom Function
Google Sheets allow you to write custom formulae that work in a similar way to the built in formulae like =SUM() or =COUNT().
Following the same steps as in workaround 2 to open the Script editor, create the following function:
function hertzify(f) {
f = f.split("-");
return f[0] + "Hz-" + f[1] + "Hz";
}
This does a similar thing as workaround 2, but instead of automatically changing the values of whatever is in a specific column, you call the function by entering the following formula in a cell:
=HERTZIFY("50-60")
This will change the cell's display value to 50Hz-60Hz like before.
You can also use this on other cells; for example if cell C3 has the text 120-130 and in cell D3 you input =HERTZIFY(C3), then D3 will display 120Hz-130Hz.
Feature Request:
As the above workarounds either process the cell data as if they are text or require the number to be formatted in a specific way, they might not be perfect workarounds for all situations.
In this case I suggest filing a feature request with Google for the ability to define a number format for a range of values in a specific cell.
You can do this by either following the Help > Report a problem menu item from the Google Sheets user interface, or make a feature request on Google's Issue Tracker asking to implement this as a feature. The link to the Issue Tracker is here

Currently I'm using the following formula to search and count the number of times a given text is used within a given cell:
=COUNTIF(Sheet1!G3:G1151, "COMPLETE")
Any ideas how I can use the same formula against multiple sheets?
Something like the following:
=COUNTIF(Sheet1, Sheet2!G3:G1151, "COMPLETE")
Thanks for your help
In case there are many sheets you want to look for, and to avoid having a to repeat the formula many times for each sheet, you can use a custom function created in Google Apps Script instead. To achieve this, follow these steps:
In your spreadsheet, select Tools > Script editor to open a script bound to your file.
Copy this function in the script editor, and save the project:
function COUNTMANYSHEETS(sheetNames, range, text) {
sheetNames = sheetNames.split(',');
var count = 0;
sheetNames.forEach(function(sheetName) {
var sheet = SpreadsheetApp.getActive().getSheetByName(sheetName);
var values = sheet.getRange(range).getValues();
values.forEach(function(row) {
row.forEach(function(cell) {
if (cell.indexOf(text) !== -1) count++;
});
});
});
return count;
};
Now, if you go back to your spreadsheet, you can use this function just as you would do with any other function. You just have to provide a string with all the sheet names, separated by a separator specified in the code (in this sample, a comma), another one with the range you want to look for, and the text you want to look for, as you can see here, for example:
=COUNTMANYSHEETS("Sheet1,Sheet2,Sheet3", "G3:G1151", "COMPLETE")
Notes:
It's important that you provide the sheet names separated by the separator specified in sheetNames = sheetNames.split(',');, and nothing else (not empty spaces after the comma, etc.).
It's important that you provide the range in quotes ("G3:G1151"). Otherwise, the function will interpret this as an array of values corresponding to the specified range, and you won't be able to look for the values in other sheets.
In this sample, the code looks for the string COMPLETE, and is case-sensitive. To make it case-insensitive, you could use toUpperCase() or toLowerCase().
If you wanted to look for all sheets in the spreadsheet, you could modify your function so that it only accepts the range and the text as parameters, and get all sheets via SpreadsheetApp.getActive().getSheets();.

To start, this is my first time posting and so please let me know if I can fix my post in any way to make it easier to answer.
I am trying to create an auto-expanding array formula
I have a sheet with my investment asset mix that including amounts of shares owned of each particular stock, and a sheet that tracks when I receive dividends. My goal is to write an automatically expanding array formula that will sum up the amount of shares that own of a stock on the date a dividend is received and return that value. I have written three different formulas that all accomplish this but none of them will auto-expand as an array.
I'm sure there are a lot of solutions I've overlooked. To boil it down, I need an expanding array formula that will sum the "Shares" column of my asset mix sheet ('Asset Mix'!D2:D, or 'AssetMixShares') conditionally. The name of the stock entered in 'Dividends'!C2:C needs to match the name of the stock in 'Asset Mix'!A2:A (or the named range 'AssetMixStocks'). It then needs to check the dates in 'Asset Mix'!C2:C (or 'AssetMixDates') against the dates in 'Dividends'!A2:A and sum all share amounts where the purchase date is less than (earlier than) the Ex-Dividend Date.
I could probably write some sort of vlookup array on the "Running Total" column -- 'Asset Mix'!E:E -- that would solve the issue, but I'm hoping to eliminate that column. I feel very strongly that what I'm trying to do should be possible without the help of a running total column -- I just don't have the knowledge.
I have tried countless functions and formulas, but the four that I currently have in my example worksheet are SUM, SUMPRODUCT, DSUM, and QUERY.
Attempt 1
SUM and IF
=ArrayFormula(SUM(IF('Asset Mix'!A:A=C2,IF('Asset Mix'!C:C<A2,'Asset Mix'!D:D))))
Attempt 2
SUMPRODUCT
=({arrayformula(SUMPRODUCT(--((AssetMixStock=(indirect("C"&ROW())))*(AssetMixDate<(indirect("A"&ROW())))),AssetMixShares))})
Attempt 3
DSUM
=DSUM('Asset Mix'!A:E,"Shares",{"Date","Stock";"<"&A2,C2})
Attempt 4
QUERY
=arrayformula(query(AssetMix,"Select sum(D) where A = '"&C2:C&"' and C < date'"&(text(year(A2:A),"0000") & "-" & text(month(A2:A),"00") & "-" & text(day(A2:A),"00"))&"' label sum(D) ''",0))
These will all work, as long as I manually drag the formula down, but I want to write some sort of formula that will auto-expand to the bottom of the Dividends sheet.
I have tried to create a Dummy sheet that has both of the relevant sheets. Please let me know if you can access it -- the link is below.

Thanks so much for getting this far and any help you can provide!
We can focus in the first formula to understand a way to make it "self-expandable". As we see it contains references to the cells A2 and C2 in "Dividends" sheet:
=ArrayFormula(SUM(IF('Asset Mix'!A:A=C2,IF('Asset Mix'!C:C<A2,'Asset Mix'!D:D))))
Every time some data appears in these columns (A and C), the formula should work. We can control the presence of the formula by onEdit trigger, if editing is manual. Consider the code:
function onEdit(e) {
var sheet = SpreadsheetApp.getActive().getActiveSheet();
if (sheet.getName() == 'Dividends') {
var row = e.range.getRow();
for (var offset = 0; offset < e.range.getHeight(); offset++) {
sheet.getRange(3, 10).copyTo(sheet.getRange(row + offset, 10));
}
}
}
It checks any modification on the sheet "Dividends" and copies required formula to the modified row(s). This way the formula is expanded for other rows in use.
Well, it's solved! I'll leave this up in case anyone else has the same question.
A kind soul explained the magic of MMULT() to me, and wrote this solution.
=ARRAYFORMULA(MMULT((C2:C=TRANSPOSE('Asset Mix'!A2:A))*(A2:A>TRANSPOSE('Asset Mix'!C2:C)),N('Asset Mix'!D2:D))
I have the following formula
=average(arrayformula(indirect(split(A1,","))))
Where A1 contains a list of cell addresses, such as E4,E6,E12. I expect this to be equivalent to =AVERAGE(E4,E6,E12), but this does not behave as expected, yielding 4 no matter what the data in the cells are. Preliminary research indicates that the INDIRECT() function doesn't pass through ARRAYFORMULA() correctly. Attempting SUM() on the outside yields precisely the same results.
Any ideas on how to average the values of cells obtained indirectly by a list of cell addresses?
I do have a list of columns and the row doesn't ever change for this average calculation, so I'm wondering if I could do some kind of subset instead, such as
=AVERAGE(RANGE){LIST_TO_SUBSET_BY}
I'm not sure about a built-in formula to do this so I've written a custom function to do it for you.
Go to Tools -> Script editor and replace the existing function with the code below and then save the project.
Now in your spreadsheet in any cell =CUSTOMFUNCTION(A1) where A1 contains a list of comma-separated cell references.
NOTE:
Updating values in the referenced cells won't force a recalculation of this formula, only updating cell A1 will.
I suggest you also go to File -> Spreadsheet settings -> Calculation and change 'Recalculation' to 'On change and every minute' that will force a recalculation of this function every minute.
/**
* Returns the average value of a dataset.
* #param {"A1"} cell The cell containing the list of cell references.
* #return The input repeated a specified nunmber of times.
* #customfunction
*/
function CUSTOMAVERAGE(cell){
var ss = SpreadsheetApp.getActiveSheet();
var array = [];
var cellRefs = cell.split(",");
for(var i in cellRefs){
array.push(ss.getRange(cellRefs[i]).getValue());
}
var sum = 0;
for(var i in array){
sum += array[i]
}
var avg = sum/array.length;
return avg;
}
Though this is a very specific application in response to this question, for the sake of the knowledge base, I'd like to show how this can be done without a script.
To give this context, imagine the LIST_CELL is a list of question numbers
(which are entered in as a header row, call the range QUESTIONS) on a test that correspond to certain standards, and the goal is to average only the questions that correspond to the standard next to which the list is written, and for each student. Using
=iferror(join(",",ArrayFormula(match(split(LIST_CELL,","),QUESTIONS,FALSE))),"")
The split function splits the a hand-entered list of questions on commas, the match function returns the column number of that particular question in QUESTIONS, and the join function joins the data back together. ArrayFormula allows the match to be performed on an array instead of just the first value.
Another single row heading lists the standards to which each question has been matched (possibly to more than one standard) by the comma separated list in LIST_CELL. For a column list of students in A:A, each standard needs to average the scores of every question that is listed next to the standard. This is accomplished by the nifty (if clunky):
average(ArrayFormula(hlookup(split(vlookup(LOOKUP_VAL,SEARCH_RANGE,COL_W_LIST),","),DATA_SOURCE,row(CURRENT_CELL))))
Breakdown from center outward:
LOOKUP_VAL is the value being looked up (the one that has multiple matches); in the example context, it's the standard.
SEARCH_RANGE is a range of cells containing both the list of lookup value (the standards in context) and the comma separated lists of column numbers generated by the first function. COL_W_LIST is the column number in the array SEARCH_RANGE that contains the list of row numbers matched from LIST_CELL.
Split takes the elements apart and placed them in a temporary array so that hlookup can be performed on each element. Via ArrayFormula the hlookup grabs each value on the same row in the appropriate QUESTIONS column - in context, it grabs the point scores for each question matched to the standard.
Finally, average is self-explanatory, and does take an array as input apparently.
These two functions in combination allow of use of indirect cell references in an array formula, and solves the much asked, "how do I include multiple matches in a calculation" question. At least in this specific context.
EDIT
There is an example "template" with this implemented here. You'll need to make your own copy to edit it.
