dudes who copy-pasted INDIRECT function into Google Sheets completely failed to understand the potential of it and therefore they made zero effort to improve upon it and cover the obvious logic which is crucial in this age of arrays.
in other words, INDIRECT can't intake more than one array:
=INDIRECT("Sheet1!A:B"; "Sheet2!A:B")
nor convert an arrayed string into active reference, which means that any attempt of concatenation is also futile:
=INDIRECT(MasterSheet!A1:A10)
————————————————————————————————————————————————————————————————————————————————————
=INDIRECT("{Sheet1!A:B; Sheet2!A:B}")
————————————————————————————————————————————————————————————————————————————————————
={INDIRECT("Sheet1!A:B"; "Sheet2!A:B")}
————————————————————————————————————————————————————————————————————————————————————
=INDIRECT("{INDIRECT("Sheet1!A:B"); INDIRECT("Sheet2!A:B")}")
the only possible way is to use INDIRECT for each end every range like:
={INDIRECT("Sheet1!A:B"); INDIRECT("Sheet2!A:B")}
which means that the best you can do is to pre-program your array like this if only part of the sheets/tabs is existant (let's have a scenario where only 2 sheets are created from a total of 4):
=QUERY(
{IFERROR(INDIRECT("Sheet1!A1:B5"), {"",""});
IFERROR(INDIRECT("Sheet2!A1:B5"), {"",""});
IFERROR(INDIRECT("Sheet3!A1:B5"), {"",""});
IFERROR(INDIRECT("Sheet4!A1:B5"), {"",""})},
"where Col1 is not null", 0)
so, even if sheet names are predictable (which not always are) to pre-program 100+ sheets like this would be painful (even if there are various sneaky ways how to write such formula under 30 seconds)
an alternative would be to use a script to convert string and inject it as the formula
A1 would be formula that creates a string that looks like real formula:
=ARRAYFORMULA("=QUERY({"&TEXTJOIN("; "; 1;
FILTER(SNAME(1); SNAME(1)<>SNAME(0))&"!A1:A20")&"}; ""where Col1 is not null""; 0)")
then this script will take the string from A1 cell and it will paste it as valid formula into A2 cell:
function onEdit() {
var sheet = SpreadsheetApp.getActive().getSheetByName('query'); // MASTER SHEET NAME
var src = sheet.getRange("A1"); // COPY STRING FROM
var str = src.getValue();
var cell = sheet.getRange("A2"); // PASTE AS FORMULA INTO
cell.setFormula(str);
}
function SNAME(option) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet()
var thisSheet = sheet.getName();
if(option === 0){ // ACTIVE SHEET NAME =SNAME(0)
return thisSheet;
}else if(option === 1){ // ALL SHEET NAMES =SNAME(1)
var sheetList = [];
ss.getSheets().forEach(function(val){
sheetList.push(val.getName())
});
return sheetList;
}else if(option === 2){ // SPREADSHEET NAME =SNAME(2)
return ss.getName();
}else{
return "#N/A"; // ERROR MESSAGE
};
}
of course, the script can be changed to onOpen trigger or with custom name triggered from the custom menu or via button (however it's not possible to use the custom function as formula directly)
this will cover all your needs to not edit the formula by adding references if new sheets are added. the only drawback is a recalculation of sheet name script... to do so you need to dismantle A1 formula for example by adding ' before the leading = pressing enter and then removing it to fix the formula
